Embodiment 1

[0017] Example 1: Toxicity determination of the mixed combination of cyprodinil and pyrimethanil against Botrytis cinerea.

[0018] In order to further understand the toxicity of the mixture of cyprodinil and pyrimethanil to Botrytis cinerea, the inventors conducted a large number of formula screening tests on the mixture of cyprodinil and pyrimethanil.

[0019] Material selection: The tomato cinerea diseased leaves were collected from the field, separated and purified in the laboratory for later use.

[0020] Test method: refer to NY / T 1156.6-2006. That is, first weigh a certain quality of 97.3% cyprodinil and 98.2% pyrimethanil original drug, add acetone to fully dissolve and then dilute with 0.1% Tween 80 aqueous solution to prepare single-dose mother liquor respectively, and set as follows according to the mixing purpose Series ratio (10:1 / 4:1 / 2:1 / 1:2 / 1:4 / 1:10). Five concentration gradients were set for each ratio.

Embodiment 2

[0027] Example 2 (50% cyprodinil · pyrimethanil suspension concentrate).

[0028] The following substances are all percentages by weight: 25% cyprodinil, 25% pyrimethanil, 4% emulsifier fatty alcohol polyoxyethylene ether, 5% calcium dodecylbenzenesulfonate, tristyrylphenol polyoxyethylene Polyoxypropylene ether 3%, antifoaming agent epoxidized soybean oil 1%, antifreeze agent glycerin 0.5%, and the balance is deionized water. Add the above formula into the mixing tank in sequence according to the proportion, and stir evenly after high shearing to prepare 50% cyprodinil · pyrimethanil suspension concentrate.

[0029] This embodiment is used for preventing and treating Botrytis cinerea, and the dosage of 50% cyprodinil·pyrimethanil suspension concentrate preparation is 60 g / mu mixed with water and sprayed, and the control effect is 85.8% and 93.9% 7 days and 14 days after the drug. The dosage of 50% cyprodinil water-dispersible granule preparation is 60 g / mu mixed with water...

Embodiment 3

[0031] Example 3 (45% cyprodinil · pyrimethanil water dispersible granules).

[0032] The following substances are all percentages by weight: 15% of cyprodinil, 30% of pyrimethanil, 6% of wetting agent sodium lauryl sulfate, 4% of dispersing agent polycarboxylate, 2% of disintegrating agent sodium chloride, Binder polyethylene glycol 3%, stabilizer soluble starch 3%, the rest is carrier kaolin. The above formula was dry crushed, granulated, dried and sieved according to the proportion to prepare 45% cyprodinil·pyrimethanil water dispersible granules.

[0033] This embodiment is used for preventing and treating gray mold of cucumber, 45% cyprodinil · pyrimethanil water dispersible granule formulation dosage 60 grams / hectare is watered and sprayed, and control effect is 82.1%, 92.5 days 7 days, 14 days after medicine. %. The dosage of 50% cyprodinil water-dispersible granule preparation is 60 g / mu mixed with water and sprayed, and the control effect is 74.2% and 81.6% 7 days...

Abstract

The invention discloses a pesticide composition containing cyprodinil and pyrimethanil, wherein the weight ratio of cyprodinil and pyrimethanil is 50:1-1:50, and preferably the weight ratio is 10:1-1:10; and the weight ratio of the sum of the weight of cyprodinil and pyrimethanil in the pesticide composition is 8%-80%. The pesticide composition of the invention is applicable to the control of botrytis cinerea of crops such as melons, vegetables, fruit trees, and the like. The pesticide composition of the invention has significant synergic effect, reduces using cost of the pesticide, and increases economic benefit.

Description

technical field [0001] The pesticide composition involved in the invention uses cyprodinil and pyrimethanil as active ingredients and is used for preventing and treating botrytis cinerea. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases, especially fungal diseases, which are of various types and cause serious damage. For a long time, chemical control has been the main effective means of disease control. In recent years, due to single and irrational use of drugs, many diseases have developed drug resistance, such as Botrytis cinerea, which has become a major problem in chemical control. At the same time, frequent use of medicines has caused the increase of farmers' medicine costs and the aggravation of environmental pollution. Therefore, there is an urgent need for high-efficiency, low-toxicity, and environmentally friendly fungicide varieties. [0003] Cyprodinil, English common name Cyprodinil. It is a pyr...
