Embodiment 1

[0023] The original drug (in this application document, the original drug refers to amino-oligosaccharidone and fludioxonil, 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:

[0024] Oligoaminosaccharins 1%

[0025] Fludioxonil 50%

[0026] Sodium lauryl sulfate (surfactant) 2%

[0027] White carbon black (filler) 5%

[0028] Vinylpyrrolidone (binder) 4%

[0029] Sodium lignosulfonate (dispersant) 5%

[0030] Attapulgite (filler) make up to 100%

[0031] The oligoaminosaccharin·fludioxonil wettable powder of this example was used to carry out the disease control experiment, the control object was watermelon wilt, and the test site was Shantou, Guangdong. The first spraying period is the seedling stage. The above wettable powder is diluted 1200 times and sprayed to irrigate the roots, and the second spraying is...

Embodiment 2

[0033] 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:

[0034] Oligoaminosaccharins 0.5%

[0035] Fludioxonil 20%

[0036] Chaku powder (surfactant) 5%

[0037] Polyvinyl alcohol (dispersion binder) 8%

[0038] Sodium lignosulfonate (dispersant) 9%

[0039] Kaolin (filler) top up to 100%

[0040] The wettable powder of amino oligosaccharin·fludioxonil of this example was used to carry out the disease control experiment, the control object was common bean root rot, and the test site was Guilin, Guangxi. The first application period is the seedling stage (about 5 cm in seedling height). Take the above-mentioned wettable powder and spray it according to 800 times dilution and irrigate the roots, and perform the second application after an interval of 10 days. Seven days after the second application, the control effect was 92.57%, and the ...

Embodiment 3

[0042]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:

[0043] Oligoaminosaccharins 2%

[0044] Fludioxonil 78%

[0045] Sodium lauryl sulfate (surfactant) 2%

[0046] White carbon black (filler) 5%

[0047] Vinylpyrrolidone (binder) 4%

[0048] Sodium lignosulfonate (dispersant) 5%

[0049] Bentonite (filler) make up to 100%

[0050] The wettable powder of amino-oligosaccharin·fludioxonil of this example was used to carry out the disease control experiment, the control object was rice blight, and the test site was Yueyang, Hunan. Take above-mentioned wettable powder and carry out seedbed spraying according to 2000 times of dilution, 10 days after application, the control effect is 95.21%, the control effect of 1000 times of control agent 2% amino-oligosaccharin aqueous solution, 1000 times of 50% fludioxonil wettable powder respectivel...

Abstract

The invention provides a pesticide composition and application thereof, wherein the active ingredients in the composition are amino oligosaccharin and fludioxonil. 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) the composition reduces the using dosage per mu of the active ingredients, saves the labor and the cost for applying the pesticide, and lowers pesticide residue and adverse effect for the environment; (3) the two active ingredients in the composition have completely different mechanisms of action, and the composition can be applied to avoid the generation of resistibility, delay the generation speed of resistibility of pathogenic bacteria and prolong the service 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 present invention relates to a pesticide composition for preventing and treating plant pathogens in agriculture, especially a fungicidal composition, more particularly a composition suitable for preventing and controlling plant soil-borne and seed-borne diseases. Background technique [0002] The prevention and control of plant root diseases (such as fusarium wilt, bacterial wilt, root rot, blight, burst disease, wilt, blight, etc.) , Reproduction and expansion, 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 or bactericidal methods, mainly thiram, hymexazol, carbendazim or acetoallin, which are mostly treated at the seedling stage o...
