Embodiment approach
[0035] As a particularly preferred embodiment of the present invention, the pesticide composition contains fludioxonil, metalaxyl and spirotetramat, and the pesticide composition also contains water, fatty alcohol polyoxyethylene ether phosphate, dodecyl Sodium alkyl sulfate, polyvinyl alcohol and ethylene glycol; the total weight of fludioxonil, metalaxyl and spirotetramat mixed with water, fatty alcohol polyoxyethylene ether phosphate, sodium lauryl sulfate, polyvinyl alcohol and The ratio of ethylene glycol can be 1:(0.5-10):(0.1-0.85):(0.05-0.4):(0.05-0.4):(0.1-0.6). In the case of this preferred embodiment, the pesticide composition can achieve a very prominent synergistic effect and exhibit high control activity against various diseases and insect pests.
[0036] Among them, the fatty alcohol polyoxyethylene ether phosphate is obtained from ether-type nonionic surfactant and phosphoric esterification, and the fatty alcohol polyoxyethylene ether phosphate monoester and di...

Abstract
The invention discloses a pesticide composition. The pesticide composition comprises fludioxonil, metalaxyl-M and spirotetramat, wherein on the basis of 1 part by weight of fludioxonil, the contents of metalaxyl-M and spirotetramat are 0.01 to 90 parts by weight and 0.01 to 90 parts by weight, respectively. The active components, i.e., fludioxonil, metalaxyl-M and spirotetramat, of the pesticide composition are combined according to a specific ratio for usage, so the pesticide composition can effectively prevent and treat a plurality of insect diseases attacking corn, wheat, peanut, cotton, paddy rice, soybean, ginseng and other crops in a mixed or successive way and is capable of increasing the output of crops, improving crop quality and soil environment and increasing the incomes of peasants. Compared with usage of a single component in or a two-component mixture of fludioxonil, metalaxyl-M and spirotetramat, the pesticide composition provided by the invention has obvious synergistic effect, and is small in usage amount and hard to incur drug resistance; and through application of the pesticide composition once, a plurality of insect diseases attacking crops in a mixed or successive way can be prevented and treated, so cost is reduced, and environmental pollution is mitigated.
Description
technical field [0001] The invention relates to the field of agricultural planting, in particular to a pesticide composition and its application. Background technique [0002] In agricultural production practice, there are often problems of mixed occurrence of different types of pests and diseases. For example, on crops such as corn, wheat, peanuts, cotton, rice, soybeans, and ginseng, cutworms, grubs, needleworms, aphids, fly Lice, leafhopper, root rot, stem rot, rust, leaf blight, smut, blight, bakanae and rotten seeds and other diseases and insect pests. [0003] For the above-mentioned common diseases and insect pests, different pesticides are often used for control. For example, cutworms are generally controlled by chlorpyrifos or phoxim, grubs are generally controlled by chlorpyrifos, wireworms are generally controlled by phoxim or carbofuran, aphids Generally, acetamiprid or carbosulfan is used for control, planthoppers are generally controlled by thiamethoxam, leafh...
