Embodiment 1

[0022] The original drug (in this application document, the original drug refers to amino-oligosaccharidone and hymexazol, which will not be described in detail below), various auxiliary agents and fillers are fully mixed, pulverized by an ultrafine pulverizer, and formulated into a wettable powder. For example the following formula:

[0023] Oligoaminosaccharins 0.3%

[0024] Hymexazol 60%

[0025] Sodium lauryl sulfate (surfactant) 2%

[0026] White carbon black (filler) 5%

[0027] Vinylpyrrolidone (binder) 4%

[0028] Sodium lignosulfonate (dispersant) 5%

[0029] Attapulgite (filler) make up to 100%

[0030] The oligosaccharin-hymexazol wettable powder of this example was used to carry out the disease control experiment, the control object was melon wilt, and the test site was Zhuhai, Guangdong. The first application period is the seedling stage (about 5 cm in seedling height). The above wettable powder is diluted 2000 times and sprayed to irrigate the roots, and th...

Embodiment 2

[0032] 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:

[0033] Oligoaminosaccharins 3%

[0034] Hymexazol 0.1%

[0035] Chaku powder (surfactant) 5%

[0036] Polyvinyl alcohol (dispersion binder) 8%

[0037] Sodium lignosulfonate (dispersant) 9%

[0038] Kaolin (filler) top up to 100%

[0039] The oligoaminosaccharin Hymexazol wettable powder of this example was used to carry out the disease control experiment, the control object was bean root rot, and the test site was Sanya, Hainan. The first spraying period is the seedling stage (about 5 cm in seedling height). Take the above wettable powder and spray it according to 1200 times dilution and irrigate the roots, and carry out the second spraying after an interval of 10. Seven days after the second application, the control effect was 91.35%, and the control effects of the control agent...

Embodiment 3

[0041] 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:

[0042] Oligoaminosaccharins 2%

[0043] Hymexazol 88%

[0044] Sodium lauryl sulfate (surfactant) 2%

[0045] White carbon black (filler) 5%

[0046] Vinylpyrrolidone (binder) 4%

[0047] Sodium lignosulfonate (dispersant) 5%

[0048] Bentonite (filler) make up to 100%

[0049] The oligoaminosaccharin·hymexazol wettable powder of this example was used to carry out the disease control experiment, the control object was rice blight, and the test site was Shaoyang, Hunan. Start spraying at the early stage of disease onset, take the above-mentioned wettable powder according to 2500-fold dilution for seedbed spraying, and spray for the second time at an interval of 10 days. 7 days after the second application, the control effect was 93.19%, and the control effects of 1000 times of 2% am...

Abstract

The invention provides a pesticide composition and application thereof, wherein the active ingredients in the composition are amino oligosaccharin and hymexazol. The pesticide composition has the advantages that (1) the composition shows excellent synergy within a certain range of mixture ratio, thus having obviously improved sterilizing effect compared with single pesticide; (2) after the pesticide effect is improved, the composition reduces the application dosage per mu of the active ingredients, lowers the using cost and reduces pesticide residue and adverse effect for the environment; (3)the two active ingredients in the composition have different mechanisms of action, and the composition can be applied to delay or overcome the drug resistibility of pathogenic bacteria and prolong theservice life of the single pesticide; and (4) the composition has broad prevention and treatment spectrum and can be used for controlling multiple fungi and bacteria diseases of crops.

Description

technical field [0001] The invention relates to a pesticide composition for preventing and treating pathogenic fungi in agriculture, especially a fungicidal composition, more particularly a composition suitable for preventing and controlling plant soil-borne diseases. Background technique [0002] The prevention and control of plant root diseases (such as fusarium wilt, bacterial wilt, root rot, blight, sudden onset disease, blight, etc.) is an important issue that is difficult to solve in current production, because the occurrence, reproduction and expansion of pathogenic bacteria in the soil cannot be solved. , pathogenic bacteria invade from the roots of plants, causing root or vascular bundles to rot. Especially in areas with suitable temperature and humidity conditions for pathogenic bacteria and continuous cropping for many years, the disease is particularly serious. At present, there are mainly two ways to prevent and control such diseases in China: 1. Bacteriostatic...
