Embodiment 1

[0024] Fully mix the original drug (in this application document, the original drug refers to cyclostrobin and triazole fungicides, which will not be described in detail below), various auxiliaries and fillers, etc., and after being pulverized by an ultra-fine pulverizer, it is prepared into a wettable powder . For example the following formula:

[0025] Cyclostrobin 8%

[0026] Myclobutanil 40%

[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 cyclostrobin-myclobutanazole wettable powder of this example was used to carry out the disease control experiment, the control object was wheat head blight, and the test site was Xiantao, Hubei. The above wettable powder is diluted and sprayed according to 2000 times, and the control effect is 93.47% after 7 days of application, and can prevent and c...

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] Cyclostrobin 30%

[0036] Diniconazole 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 wettable powder of cyprostrobin-diniconazole in this example was used to carry out the disease control experiment, the control object was wheat head blight, and the test site was Anqing, Anhui. Take the above wettable powder and spray it according to 1500 times dilution, the control effect is 94.32% 7 days after the application, the control effect of the control agent 25% cyclostrobin suspension concentrate 1000 times, and the 12.5% ​​diniconazole WP 1000 times are 85.17% respectively. %, 76.65%.

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] Cyclostrobin 25%

[0045] Difenoconazole 25%

[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 wettable powder of cyprostrobin and difenoconazole in this example was used to carry out the disease control experiment, the control object was watermelon wilt, and the test site was Lingshui, Hainan. Take the above-mentioned wettable powder according to 2000 times dilution spray and root irrigation, the control effect is 95.18% 7 days after the application, the control effect of the control agent 25% cyclostrobin suspension concentrate is 1000 times, and 25% difenoconazole EC is 1000 times. They are ...

Abstract

The invention provides a pesticide composition and application thereof, wherein the composition comprises the active components, namely JS399-19 and a triazole bactericide, and the composition is suitable for controlling agricultural diseases. The pesticide composition has the following advantages: (1) the composition shows excellent synergistic action in certain proportioning range, the sterilizing effect of the composition is improved obviously compared with a single agent, and simultaneously the dosage, the application labor and the cost of the pesticide are reduced, and harmful effect and pesticide residue to the environment are also reduced; (2) the two active components in the composition have different mechanisms of action, and the application of the composition can retard or overcome the drug resistance of pathogenic bacteria and prolong the service life of the single agent; and (3) the composition has wide control spectrum and can control various crop diseases.

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 various types of Fusarium. Background technique [0002] Wheat head blight is also known as wheat ear dry, rotten wheat head, red wheat head. Mainly cause seedling rot, ear rot, stem base rot, stalk rot and ear rot, which can be damaged from seedlings to heading. Among them, the most serious impact is ear rot. The pathogen of wheat scab is Fusarium graminearum. Wheat head blight is a typical climate disease and one of the important diseases that affect the yield and quality of wheat. Its occurrence and development are closely related to the amount of bacteria source and meteorological factors such as temperature, humidity, rainy days, and sunshine. Especially during the period of wheat heading and flowering, high temperature and high humidity weather conditions will be ...
