Friends new to a lot of meat too much meat plant for some time, often not quite understand why so many people are online more meat is required insecticide sterilization is needed, what sooty mold Alternaria what is the root scale insects mealybugs, and he seems no need for this, is it because of his genius, it is kind of more of a meat expert, so no problems in this regard. Of course, not like this, and the outbreak of pests and diseases usually takes a period of time, with the accumulation of time and enrichment, which is why farmers uncle to be the same piece of land to crop rotation, one of the reasons some crop pests and diseases in order to avoid some kind of invasion dye intensified. So, even if you do not have a variety of harmful bacteria problems, or honestly conceal this article, because more meat as long as a year or two species, as long as you do not medication, basic sooty mold is run. Author below: grinning Yeah nodded, sorting out a pair succulents bactericidal drug is more practical, and introduces the dosage, while noting that some of the dangers of pesticides, it is worth considering.

Succulents from the soil to the leaves with a plug, it seems that every step of the standard procedure, so long as it is not according to an accident. In fact, the final analysis are sick external reasons. Water Congress rotten, we will all know black rot of water, so water control. However, the culprit of the water is black rot fungus, fungi infested water big lead, also caused soil fungi hypoxia malignant growth, and finally defeated the plant cuticle defense, invaded the body, because the plants and animals are not immune, the bacteria enter the plants can be said is rampant unimpeded, so there will be black rot night dead legends. So, in addition to controlling water there any way to prevent the disease happen, and that is sterilization.

If planting method can prevent the disease from the source, then the drug is in the middle blocking the enemy. Moreover, the drug more than a minute, in addition to prevention and treatment of diseases of bactericidal drug and insecticide, as well as plant growth regulating agents, in addition to fertilizer.

The first is bactericidal drugs, followed by insecticide, the last plant regulators and fertilizers. Only introduces Dosage, common sense would say, to think further Friends meaty flesh planted helpful. I Postgraduate, objective blunt terms, we do not mind, there are deficiencies noted at the welcome large coffee. The following start into the topic.

Pesticide Considerations Overview:

1, select pesticides

Many varieties of pesticides on the market, pesticide varying quality, control objects are quite different, so be sure to select the pesticide according to the object to be controlled, so that symptomatic treatment, do not blindly medication. Fungus infection sterilizing drugs, pests with insecticide, lack of nutrition with fertilizer, with plant growth regulating plant growth regulators (ABT and the like). Try to look for the big brands, such as, the light, the people, gram wins, DuPont ......

2, formulated pesticides

To accurately weighed quantity of a drug and the amount of water and can not increase or decrease the concentration, in strict accordance with the requirements described in blending. Especially the concentration of plant growth regulator on very sensitive. First with a small amount of water into the mother liquor further dilution.

3. The application of pesticides

First, we must choose the appropriate instruments, such as fungicide spray droplet to select smaller nozzle; spray insecticide optional larger nozzle. Two administration depends on the weather, windy, rain is not spraying; not spraying before the rain; dew not spray; sun at high temperatures can not spraying. At high temperatures, highly volatile pharmaceutical drugs into the body through breathing, skin pores, the operator can easily lead poisoning. To try to choose sunny windless conditions, generally 8-10 o'clock in the morning (after the dew dried), 5-7 o'clock in the afternoon (around sunset), select pest activity exuberant time spraying. Third, we must take the appropriate application techniques depending on the control object. For example, bacteria are generally on the back of crop leaves, leaf on the back when spraying sure to spray evenly, generally occurs in the young shoots of aphids, mites, mostly in the back of the old blade bore, scale insects and larvae in the roots. In addition, bactericidal drug can generally be directly put on the wound plants.

4, security

Pesticides are ***, in the course of time pay attention to their own safety, to prevent lead poisoning. Wear necessary masks, protective clothing, gloves, and other protective equipment; prohibition period spraying smoking, eating, drinking; when spraying, to stand in the wind; timely cleaning the body after application, replacement clothing.

5, waste disposal

After spraying, the remaining liquid and wash the sprayer with water should be properly handled and can not fly-tips, never poured into rivers and lakes reservoir pond, pay attention to environmental protection.

6, to avoid resistance

Fungicides and insecticides should always different from the other mechanisms of drug action rotating, reducing drug resistance.

7, a total ban on the use of pesticides (23 kinds)

BHC (HCH), DDT (DDT), toxaphene, DBCP, chlordimeform, ethylene dibromide (EDB), nitrofen, aldrin, dieldrin, mercury preparations, arsenic, Lead class enemy dead twin, fluoroacetamide, Gan fluorine, tetramine, fluorine, sodium acetate, rat poison silicon, methamidophos, parathion, methyl parathion, monocrotophos, phosphamidon.

8, limit the use of pesticides (18 kinds)

Prohibits oxygen dimethoate use on cabbage; Dicofol and fenvalerate ban on the use of tea; ban daminozide (daminozide) for use on peanuts; prohibit the use of terbufos on sugar cane; prohibit phorate, armor group isofenphos, terbufos, methyl phosfolan, sulfotep, uptake of phosphorus, carbofuran, aldicarb (protagonist Shandong "poison Ginger" event), ethoprophos, phosfolan, coumaphos, fonofos, chlorazol phosphorus, fenamiphos use on vegetables, fruit, tea, Chinese herbal medicine. (Learn more about some of it anyway)

First, fungicide

Agricultural fungicides for controlling plant diseases caused by a variety of pathogenic microorganisms of a class of pesticides, generally refers to fungicides.

Distinguish between the absorption and non-absorption of fungicides

1, Fungicide can plant leaves, stems, roots, seeds absorption into the plants, the plants transporting body fluids, diffusion, retention or produce metabolites, can prevent some of the plants or seeds deep into the inner endosperm diseases, in order to protect crops against pathogens or disseminated have been susceptible to treatment plants, it has a therapeutic effect. Such as carbendazim, Lectra bacteria, Green Hang the 2nd, more mold clean, Peronophythora clear, Tetracyclines copper, metalaxyl, fosetyl, thiophanate-methyl, Fenaminosulf, triadimefon, A cream copper, Sandofan , double dressing, etc. (interested themselves look usage, just say here that some of the more commonly used drugs meat).

2, refers to a non-systemic fungicide agents can not be sucked inside the plant and conduct, retention, also called protective fungicides. Most species are non-systemic fungicide, such agents is not easy to make pathogens resistant, more economical, but most only have a protective effect, could not prevent further disease in plants. Such as zinc sulfate, copper sulfate, dodine, chlorothalonil, copper green milk, surfactants, builders, sulfur mixture, ash, Bordeaux mixture, mancozeb, thiram and so on.

Bactericidal drugs commonly used detailing

1, carbendazim

Within carbendazim fungicide efficiency and low toxicity, have the absorption treatment and protection. People, animals, fish, bees and other low toxicity. Skin and eye irritation, mouth *** by now dizziness, nausea, and vomiting. No carcinogenic, teratogenic, mutagenic effect (this is very important, try not to use drugs carcinogenic, teratogenic and mutagenic drugs are pregnant women, families can not stick).

The main forms: 25%, 50% WP, 40%, 50% SC, 80% water dispersible granule.

Consumption usage :( 50% WP prevail, other concentrations calculated ratio, which should not have taught, will not or do not look down)

(1) spraying, household use 50% of carbendazim 800 to 1000 times, spraying times and determine the dose according to progression of the disease situation, every 7 to 10 days, spray once.

(2) IRRIGATING concentration with the spraying, filling about 10 days every 1, 2 or 3 times and even irrigation can.

(3) mixed with soil, use 1 gram of one liter of soil, planting soil with medicine.

(4) Seed soaking, per 100 grams of seed dressing with 1 g. Soaking method may also be used, diluted 500-fold with carbendazim 2 g, 1 liter watered soaking two hours.

Precautions:

(1) The spraying should be selected cloudy or sunny afternoon, within six hours after the rain should fill spray jet.

(2) carbendazim fungicide can be mixed with the general, but with the insecticide, miticide to mix with the mix with the use.

(3) can not be mixed with alkaline drugs or copper fertilizer formulations.

(4) dilution of liquid such as delamination occurs after temporarily not in use after the need to shake.

(5) The devaluation Guoguang carbendazim, recognized as the best domestic. I feel really good to use, just give a little, when other brands dissolve easily sticky bottom, it is easy to precipitate dissolved, the light of a punch to dissolve, never dip the end, put half an hour and no significant precipitation. Easy to dissolve, not precipitate, it shows fine powder, it is not easy to plug nozzles, damage watering can.

2, chlorothalonil

Chlorothalonil is a broad-spectrum protective fungicides, no uptake role, but then sprayed onto the plant, to have a good adhesion on the surface, it can not easily be washed away by rain, so the long term efficacy. Low toxicity fungicides chlorothalonil, minority skin irritation, eye for some people there is a significant stimulating effect on fish toxicity (home to raise fish to be very careful). Under the experimental conditions no teratogenic, mutagenic effect.

The main forms: 40% SC, 50%, 75% WP, 75% WDG, 10% oil, 5%, 25% granules, 2.5%, 10%, 30%, 45% smoke , 5% powders.

Dosage :( subject to 75% wettable powder)

Spraying diluted 500-800 times, depending on the occurrence of disease, the administration once every 7 days or so, continuous medication 2-3 times, when to spray evenly through spraying. Because it is a protective fungicide, equivalent to plant surfaces form a protective film, so each one must be uniformly covered with leaves and branches, especially in the back, do not forget the leaves.

Precautions:

(1) For carbendazim resistant disease, use of chlorothalonil better. (I have many years of experience, carbendazim + chlorothalonil, it can be said to be invincible)

(2) fish farming process should be used with caution.

Be careful not to mix with Bordeaux mixture, lime sulfur and other alkaline pesticides (3) to use.

(4) rose chlorothalonil is essential drugs for the prevention and treatment of various fungal diseases such as black spot, leaf spot, rust, powdery mildew, downy mildew, gray mold, anthracnose, blight, leaf scorch disease, scab, leaf curl, perforation disease, almost universal.

3, triadimefon

Triazolone called triadimefon, Barry pass, was the first widely used triazole fungicides. Powdery mildew, rust and smut effects, and thus have a good reputation: "triadimefon." Triazolone is an efficient, low toxicity and residue, long duration, the absorption of strong triazole fungicides. For rust and powdery mildew prevention, eradication, treatment and other effects (eradicate role is to eradicate the strongest). Mild skin irritation, moderate toxicity to fish, bees and birds to humans. In the test dose non-carcinogenic, teratogenic, mutagenic effect.

The main forms: 5%, 15%, 25% wettable powder, 25%, 20%, 10% EC, 20% paste, 25% suspension concentrate, 0.5%, 1%, 10% powder, 15% aerosol .

Dosage :( subject to a 15% wettable powder)

(1) spraying, 15% wettable powder 500-2000 times, I recommend 1,500 times, 1,000 times ill, decided spraying frequency and dosage according to progression of the disease situation, every 7 to 10 days, spray once.

(2) dressing, per 300 grams of seed dressing with 1 gram charge (not recommended).

Precautions:

(1) triazolone can be mixed with alkaline agents, not with copper preparations mix.

(2) the seed dressing may delay emergence 1-2 days, but does not affect the growth rate of emergence and post

(3) No specific antidote, only symptomatic treatment. (I know much of it)

(4) aquaculture areas away from drug ban in rivers and ponds and other water cleaning application equipment; avoid contamination of liquid water source.

(5) or devaluation Guoguang, because as with carbendazim.

4, hymexazol

Hymexazol hymexazol also known, is a new absorption of soil fungi fungicides and plant growth regulators. Its unique mechanism of action. After being absorbed into the soil and the soil and the soil inorganic metal salts interact more effectively suppress the pathogen spore germination and mycelial growth, while promoting plant growth, tillering root, root hair growth, root activity increased, enhanced seedling cold tolerance, improve the quality of seedlings, to healthy seedlings, seedlings role. Hymexazol high permeability, two hours will be able to move to the stem, 20 hours to move the plant body. Hymexazol been recognized case of pollution-free pesticides, its physical and chemical properties of indicators in full compliance with environmental requirements.

The main forms: 8%, 15%, 30% water, 15%, 70%, 95%, 96%, 99% WP, 20% EC, 70% seed treatment dry powder.

Dosage :( 30% water, whichever)

(1) spraying, diluted 1200-1500 times, decided spraying frequency and dosage according to progression of the disease situation, every 7 to 10 days spray once, 2-3 times.

(2) IRRIGATING 600-800 diluted liquid.

(3) soaking, diluted 1000 fold.

Precautions:

(1) may be mixed with the general pesticide and mutually reinforcing.

(2) low toxicity and no residue secure, environmentally friendly fungicides, pesticides are the preferred green food.

(3) low toxicity and environmental protection is an advantage, but after all poisonous, do not effect. Suicide even, low toxicity dead slow living death.

5, mancozeb

Mancozeb is a good protective fungicides, low toxicity pesticides. Because of its wide range of sterilization, easy to produce resistance, prevention is better than other similar fungicide, so in the international arena has been a large amount of tonnage of products. Agents on the skin and mucous membrane irritation, toxic to fish.

The main forms: 70% and 80% WP Mancozeb 80% spray grams, Tai Sang M-45, the new Wan-sheng, a wettable powder.

Dosage :( subject to 80% wettable powder)

Spraying diluted 800-1000 times, depending on the disease occurrence, 10-15 days spraying time, continuous medication 2-3 times, when spraying to spray evenly through every. Because it is a protective fungicide, equivalent to plant surfaces form a protective film, so each one must be uniformly covered with leaves and branches, especially in the back, do not forget the leaves.

Precautions:

(1) during storage, it should pay attention to prevent heat, and to keep dry, so in hot, humid conditions decomposition agents, reduce the efficacy.

(2) can not be mixed with alkaline or copper agents.

(3) toxic to fish, do not pollute the water.

(4) agents on the skin and mucous membrane irritation, pay attention when you use protection.
