Problems solved by technology

However, long-term use of a single type of fungicide will cause different degrees of disease resistance and reduce the control effect
At present, for the prevention and control of diseases that are prone to resistance, the main method is to develop new pesticide ingredients that have no cross-resistance with existing pesticide varieties or to compound the existing pesticide varieties. The cycle is long, and the current development speed is far behind the speed of drug resistance

Embodiment 1、61

[0012] Example 1. 61% Picoxystrobin·Benoxanone wettable powder (60:1)

[0013] Picoxystrobin 60%, benzophenone 1%, fatty alcohol polyoxyethylene ether 5%, sodium lignin sulfonate 7%, calcium dodecylbenzene sulfonate 5%, diatomaceous earth makes up to 100%. The picoxystrobin, benzophenone, wetting and dispersing agent, and filler are evenly mixed, and then pulverized by a jet mill, and then stirred for 30 minutes.

Embodiment 2、45

[0014] Example 2. 45% picoxystrobin·benzophenone water dispersible granules (1:8)

[0015] Picoxystrobin 5%, benzophenone 40%, lignosulfonate 5%, sodium dodecylbenzene sulfonate 5%, sodium sulfate 10%, ammonium chloride 3%, and kaolin make up to 100%. Mix picoxystrobin, benzophenone, wetting and dispersing agent, disintegrant, and filler evenly, pulverize by jet mill, stir for 30 minutes, knead, and then add to fluidized bed granulation dryer for granulation. Dry well.

Embodiment 3、30

[0016] Example 3. 30% Picoxystrobin·Benoxanone suspension (1:2)

[0017] Picoxystrobin 10%, benzophenone 20%, alkylphenol polyoxyethylene ether 7%, calcium dodecylbenzene sulfonate 8%, xanthan gum 2%, ethylene glycol 1%, water to 100% %. First, picoxystrobin, benzophenone, and emulsifier are ground in a ball mill for 2.5 hours, then pumped into the shearing machine and mixed with antifreeze, thickener, water, and mixed evenly through high-speed shearing. .

Abstract

The invention relates to a bactericidal composition containing picoxystrobin and metrafenone. A weight ratio of active ingredients, namely picoxystrobin and metrafenone, is preferably (1-40):(40-1), further perferably (1-20):(20-1); and the bactericidal composition comprises 1-85% by mass of the active ingredients and the balance of auxiliary ingredients allowed to be used and accepted in pesticides. A dosage form of the bactericidal composition is a water dispersible granule, wettable powder, a suspending agent, aqueous emulsion, microemulsion and the like, and the bactericidal composition ismainly used for preventing and controlling wheat scab and wheat powdery mildew.

Description

Technical field: [0001] The invention belongs to the field of agricultural fungicides, and specifically relates to a fungicidal composition containing picoxystrobin and benzophenone and its application for preventing and treating wheat diseases. Background technique: [0002] Picoxystrobin is a systemic fungicide with a broad spectrum of control objects. It is mainly used to control wheat foliar diseases such as leaf blight, leaf rust, glume blight, brown spot, powdery mildew, etc., and other meth Picoxystrobin has a stronger therapeutic effect on wheat leaf disease, net spot disease and moire disease compared with acrylate fungicides. [0003] Benzophenone is a benzophenone fungicide developed by BASF. It is mainly used for the prevention and treatment of various diseases of Ascomycotina, especially for crop powdery mildew. It can protect, treat, eradicate and inhibit the production of various powdery mildew. The role of spores. [0004] Wheat is the most important cereal crop in ...
