Embodiment 1

[0024] Fully mix the original drug (the original drug methoxyacrylate fungicide in this application document and pyrithrimol or pyrithrimol sulfonate or pyrimol, which will not be described in detail below), various auxiliary agents and fillers, etc., after After being pulverized by an ultra-fine pulverizer, it is formulated into a wettable powder. For example the following formula:

[0025] Kresoxim-methyl 30%

[0026] Pyrimetholsulfonate 1%

[0027] Sodium lauryl sulfate (surfactant) 2%

[0028] White carbon black (filler) 5%

[0029] Vinylpyrrolidone (binder) 4%

[0030] Sodium lignosulfonate (dispersant) 5%

[0031] Attapulgite (filler) makes up to 100%.

[0032] The disease control experiment was carried out by using the wettable powder of kresoxim-methyl pyrithrimol sulfonate of this example, the control object was apple powdery mildew, and the test site was Yantai, Shandong. Take above-mentioned wettable powder and spray according to 2000 times of dilution, 7 day...

Embodiment 2

[0034] The original drug, various additives and fillers are fully mixed, pulverized by an ultra-fine pulverizer, and then formulated into a wettable powder. For example the following formula:

[0035] Azoxystrobin 30%

[0036] Acetrimol 1%

[0037] Chaku powder (surfactant) 5%

[0038] Polyvinyl alcohol (dispersion binder) 8%

[0039] Sodium lignosulfonate (dispersant) 9%

[0040] Kaolin (filler) makes up to 100%.

[0041] The azoxystrobin-pyrimol wettable powder of this example was used to carry out the disease control experiment, the control object was wheat powdery mildew, and the test site was Xinyang, Henan. Get above-mentioned wettable powder and spray according to 2000 times of dilution, 7 days after the medicine, the control effect is 94.35%, the control effect of 25% azoxystrobin suspension concentrate 2000 times of contrast agent, 25% azoxystrobin suspension concentrate 500 times is respectively 85.18%, 500 times. 76.43%.

Embodiment 3

[0043] The original drug, various additives and fillers are fully mixed, pulverized by an ultra-fine pulverizer, and then formulated into a wettable powder. For example, the following formula:

[0044]Enoxastrobin 30%

[0045] Dimethicol 1%

[0046] Sodium lauryl sulfate (surfactant) 2%

[0047] White carbon black (filler) 5%

[0048] Vinylpyrrolidone (binder) 4%

[0049] Sodium lignosulfonate (dispersant) 5%

[0050] Bentonite (filler) was made up to 100%.

[0051] The disease prevention and control experiment was carried out using the wettable powder of oxastrobin·pymetrozine in this example. The control object was dahlia powdery mildew, and the test site was Yulu, Baoan, Shenzhen. Get above-mentioned wettable powder and spray according to 2000 times of dilution, 7 days after the drug, the control effect is 92.51%, and the control effect of contrast agent 25% erythystrobin EC 2000 times, 25% pyrimol EC 500 times is respectively 83.27%, 74.35%.

Abstract

The invention provides a pesticide composition and application thereof. The active components in the composition comprise methoxyl acrylic ester bactericide and pyrimidine bactericide (ethirimol or ethirimol sulphonate or dimethirimol); and the composition is suitable for controlling diseases in the agriculture. The pesticide composition has the following advantages: (1) the composition shows perfect synergy in a certain matching range, remarkably improves the bactericidal effect compared with a single dosage, simultaneously reduces the using dosage of the pesticide, application labor and cost, and also reduces adverse effect on the environment and pesticide residue; (2) two effective components in the composition have different action mechanisms, so the application of the composition can delay or overcome the pesticide resistance of pathogenic bacteria and prolong the service life of the single dosage; and (3) the composition has broad prevention and control spectrum, and can control various diseases of crops.

Description

technical field [0001] The invention relates to a pesticide composition, which is used for preventing and treating pathogenic fungi in agriculture, and is especially suitable for preventing and controlling pathogenic fungi of the Ascomycotina subphylum. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. Mostly ectoparasitic, all or most of the mycelium is exposed on the surface of the leaves, stems, shoots, buds, flowers and fruits of the host plant, and produces a large number of mycelia, conidiophores and conidia A white powder visible to the naked eye. [0003] Powdery mildew is widespread all over the world, especially in dicotyledonous plants. The main powdery mildews in China include cereal powdery mildew caused by Ery-siphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea ; Grape powdery mildew caused by Uncinula necator; Powdery mildew of more than 80 kinds o...
