Embodiment 1

[0024] The original drug (the original drug in this application document refers to morpholine fungicides such as pyrimethol and tridemorpholine, fenfenmorph, dodemorpholine, etc., will not be described in detail below), various auxiliary agents and fillers, etc. Mix and pulverize with a superfine pulverizer to prepare wettable powder. For example the following formula:

[0025] Acetrimol 15%

[0026] Trimorpholine 65%

[0027] Sodium lauryl sulfate (surfactant) 2%

[0028] White carbon black (filler) 5%

[0029] Vinylpyrrolidone (binder) 4%

[0030] Sodium lignosulfonate (dispersant) 5%

[0031] Attapulgite (filler) make up to 100%

[0032] The disease control experiment was carried out by using the pyrimol·tridemorph wettable powder of this example, the control object was cucumber powdery mildew, and the test site was Zhaoqing, Guangdong. Get above-mentioned wettable powder and spray according to 2000 times of dilutions, and control effect is 95.32% after 7 days of med...

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] Acetrimol 1%

[0036] Fenpropimorph 50%

[0037] Chaku powder (surfactant) 5%

[0038] Polyvinyl alcohol (dispersion binder) 8%

[0039] Sodium lignosulfonate (dispersant) 9%

[0040] Kaolin (filler) top up to 100%

[0041] The disease control experiment was carried out by using the pyrimol·fenpropimorph wettable powder of this example, the control object was powdery mildew of melon, and the test site was Zhuhai, Guangdong. Get above-mentioned wettable powder and spray according to 1500 times of dilution, 7 days after the medicine, the control effect is 94.27%, and the control effect of 1000 times of contrast agent 25% pyrimethol suspension concentrate, 1000 times of 75% fenpropimorph emulsifiable concentrate is respectively 84.35%, 1000 times. 75.16%.

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] Acetrimol 2%

[0045] Dodecamorph 60%

[0046] Sodium lauryl sulfate (surfactant) 2%

[0047]White carbon black (filler) 5%

[0048] Vinylpyrrolidone (binder) 4%

[0049] Sodium lignosulfonate (dispersant) 5%

[0050] Bentonite (filler) make up to 100%

[0051] The disease control experiment was carried out by using the pyrimol·dodecyclomorph wettable powder of this example, the control object was wheat powdery mildew, and the test site was Anyang, Henan. Get above-mentioned wettable powder and spray according to 1500 times of dilution, 7 days after the drug, the control effect is 95.47%, the control effect of 1000 times of contrast agent 25% pyrimol suspension concentrate, 500 times of 40% dodecyclomorph emulsifiable concentrate is respectively 86.34% , 76.51%.

Abstract

The invention provides a pesticide composition and an application thereof, wherein the composition comprises the following active gradients: ethirimol and morpholine fungicides (tridemorph, fenpropimorph, dodemorph, and the like); and the composite is suitable for preventing and treating diseases in agriculture. The pesticide composition has the following advantages: (1) the composition shows excellent synergic effect in a certain matching range, remarkably improves the sterilization effect compared with single dosage, reduces the using dosage of pesticide, the application employees and the cost simultaneously, and decreases adverse effects on environment and pesticide residue; (2) since the two effective gradients in the composition have different action mechanisms, the application of the composition can delay or overcome the drug resistance of pathogenic bacteria and prolong the service life of the single dosage; and (3) the composition has wide prevention and treatment spectrum and can prevent and treat a plurality of diseases of crops.

Description

technical field [0001] The invention relates to a pesticide composition for preventing and treating pathogenic fungi in agriculture, especially a bactericidal composition, more particularly a composition 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; Po...
