Embodiment 1

[0046] 51% benzamid · azoxystrobin wettable powder

[0047] Benzamid 50%

[0048] Azoxystrobin 1%

[0049] Sodium lauryl sulfate (wetting agent) 2%

[0050] Sodium lignosulfonate (dispersant) 5%

[0051] White carbon black (filler) 10%

[0052] Kaolin (filler) top up to 100%

[0053] The active ingredients, various additives and fillers are fully mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, a 51% benzamid · azoxystrobin wettable powder can be obtained.

[0054] This embodiment is applied to the control of cucumber downy mildew. 51% benzamid · azoxystrobin wettable powder is diluted with water at 150g (a.i.) / ha [a.i., active ingredient, ie active ingredient] and sprayed, and the control effect is 92.8% within 7 days after application. The azoxystrobin in this example can be replaced by methoxyacrylate fungicides such as kresoxstrobin, trifloxystrobin, enotristrobin, methoxystrobin, pyraclostrobin, and dikestrobin...

Embodiment 2

[0059] 62% benzamid · kresoxim-methyl water dispersible granules

[0060] Benzamid 60%

[0061] Kresoxim-methyl 2%

[0062] Sodium alkylnaphthalene sulfonate (wetting agent) 5%

[0063] Sodium lignosulfonate (dispersant) 7%

[0064] Sodium lauryl sulfate (dispersant) 2%

[0065] Ammonium sulfate (disintegrant) 5%

[0066] Light calcium carbonate (filler) makes up to 100%.

[0067] Mix the active ingredient, dispersant, wetting agent, disintegrating agent and filler uniformly according to the ratio of the formula, crush it into a wettable powder by airflow, add a certain amount of water, mix and extrude the material, and obtain 62 after drying and sieving % benzamid · kresoxim-methyl water dispersible granules.

[0068] This embodiment is applied to control grape downy mildew. 62% benzamid · kresoxim-methyl water-dispersible granules were diluted with water at 120g (a.i.) / ha and sprayed, and the control effect was 93.7% 7 days after the application. The azoxystrobin in ...

Embodiment 3

[0073] 21% benzamid · erythoxystrobin EC

[0074] Benzamid 20%

[0075] Ethoxystrobin 1%

[0076] N-methylpyrrolidone (solvent) 10%

[0077] Nongru 1601# (emulsifier) ​​5%

[0078] Nongru 500# (emulsifier) ​​5%

[0079] Xylene (solvent) was made up to 100%.

[0080] The active ingredient, emulsifier and auxiliary agent are sequentially added into the mixing tank according to the ratio of the formula, and stirred evenly to prepare 21% benzamid-enoxastrobin emulsifiable concentrate.

[0081] This embodiment is applied to control potato late blight. 21% benzamid · enoxastrobin EC was diluted and sprayed at 180g (a.i.) / ha with water, and the control effect was 93.6% 7 days after application. The azoxystrobin in this example can be replaced by methoxystrobin fungicides such as azoxystrobin, kresstrobin, trifloxystrobin, azoxystrobin, pyraclostrobin, dikestrobin, etc., the effect basically the same.

Abstract

The invention provides a pesticide composition which contains the following active components with effective quantity: zoxamide and one of strobilurin fungicides. The pesticide composition can be used for preventing and treating various diseases of crops and has the following advantages: 1. the blending has remarkable synergic effect and improves the prevention and treatment effects; 2.the composition has two effective ingredients with different functional mechanisms, decreases the single selection pressure of harmful bacteria and is convenient for overcoming and delaying the occurrence of drug resistance among germs; and 3. the drug blending reduces the dosage so as to reduce the cost and the environmental pollution.

Description

Technical field [0001] The invention belongs to the technical field of pesticides and relates to a pesticide composition, and in particular to a pesticide composition that can be used to prevent and treat various agricultural diseases and has a synergistic effect. Background technique [0002] In recent years, due to single use of drugs and unscientific use of drugs, many pathogenic bacteria have become resistant to currently used pesticides. Resistance to powdery mildew, gray mold, downy mildew, etc. is very common and has become a major problem in chemical control. . As pathogenic bacteria develop resistance, farmers frequently apply pesticides, which increases the burden and environmental pollution. Therefore, there is an urgent need for new varieties of fungicides that are efficient, low-toxic, safe, and environmentally friendly. [0003] Zoxamide is a highly effective protective amide fungicide with long lasting effect and good resistance to rain erosion. It has a uni...
