A brief discussion on the mixed application technology of fungicides, pesticides, regulators, foliar fertilizer, etc.

In the whole process of planting crops, many growers will apply a lot of mixtures, such as fungicides and fungicides or other types of chemical fertilizers mixed now, which can reduce drug resistance, improve efficacy, and reduce the cost of medication. Therefore, the next web editor will briefly talk about the mixing technology of fungicides and pesticides, regulators, leaf fertilizers, etc., hoping to have some assistance to everyone.

I. Several types of conditions in which mixtures or mixtures must be applied

1. Composition of disinfectant, disinfectant and insecticide

For example, a mixture of a whitefly or budworm preventive drug (acetamiprid) and a downy mildew preventive drug (mefenoxaline, mancozeb) or a gray mold preventive drug (iprodione, niacinamide, fludioxonil)

2. Composition of fungicide and microbial naphthylacetic acid

For example, farmers widely mix auxin 2,4-D with fungicides (fludioxonil, pyrimethanil, etc.) to prevent gray mold and wipe tomato flower buds (or dip flowers).

3. Composition of fungicide and leaf fertilizer

4. Composition of disinfectant and barrel mixed modifier

II. Differences between mixed traditional Chinese medicine preparations and mixed applications

1. Mixed Chinese medicine preparations are different from mixed applications.

2, mixed application is based on fertilizer users must be mixed fertilizer application.

3. The mixture is a technical traditional Chinese medicine preparation produced and processed in advance, and farmers have long been unable to change the composition of the ingredients when applying it.

III. Common problems of fungicide mixing

1. There is no inhibitory effect after mixing drugs.

2. Add another fungicide or other chemical fertilizer or fertilizer after configuring a disinfectant solution. If floc precipitation occurs or discoloration, stratification, bubbling, etc. occur, it indicates that the disinfectant cannot be mixed with this chemical fertilizer or fertilizer.

IV. Several types of conditions in which drugs cannot be mixed

1. Oxfrost·manganese zinc and metalaxyl·mancozeb;

2. Metalaxyl, mancozeb and aurorin, azoxystrobin and kresoxystrobin;

3. pyraclostrobin and pyraclostrobin·dimetrien;

4. Flufenican·propamocarb and propamocarb;

5. Difenoconazole and myclobutanil;

6. Dimethomorph, mancozeb and dimethomorph;

7. iprocarbamide and butadiene sclerotium;

8. Triadimefon and thiophanate-methyl;

9. Mixtures containing mancozeb can no longer be mixed with mancozeb;

10, copper traditional Chinese medicine preparations generally can not be mixed with alkali fertilizer.

V. Strongly recommend several types of barrel mix composition

1, cucumber downy mildew, downy mildew, gray mold damage is more serious

68.75% flufenoxam·propamocarb SC 10% difenoconazole WDG 50% fludioxonil WP or 50% nicotinamide WDG

2, tomato late blight, gray mold, leaf mold, early blight damage is more serious

68% metalaxyl·mancozeb water dispersible granules 32.5% azoxystrobin·difenoconazole suspension or shigao huiyou or niacinamide

3. Tomato gray mold, loofah gray mold, strawberry seedling gray mold, pepper gray mold damage is more serious

Nicotinamide 50% WDG 25% pyraclostrobin EC

4, prevention of downy mildew, gray mold, downy mildew, late blight

56% azoxystrobin·chlorothalonil suspension, 32.5% azoxystrobin·difenoconazole suspension, azoxystrobin difenoconazole chlorothalonil, difenoconazole chlorothalonil

5, prevention of melon vegetable crops anthracnose

Triadimefon sulfur powder.

6. Antiviral treatment and improvement of crop disease resistance

Antiviral drugs, leaf nutrients.

VI. Clarify the concentration value used in the barrel mixture

According to the concentration value of dilution solution effective for diseases, such as downy mildew and gray mold prevention, the concentration value of 68.75% flufenoxam·downy mildew suspension is 600 times that of 25% niacinamide water dispersible granule, and 1500 times that of water dispersible granule is mixed for immediate use to prevent diseases and pests.
