Abstract

The invention discloses a guadipyr-containing flowable concentrate for seed coating as well as a preparation method and application of the flowable concentrate for seed coating. The guadipyr-containing flowable concentrate for seed coating is prepared from the following raw materials by mass percent: 5-30% of guadipyr, 3-10% of a wetting dispersant, 2-10% of a film-forming agent, 0.1-0.5% of a thickening agent, 1-10% of an anti-freezing agent, 0.2-1% of an antifoaming agent and the balance of water. In order to improve the treating effect of the drug, the flowable concentrate for seed coating also can be prepared from the components such as imidacloprid, myclobutanil, chlorpyrifos and difenoconazole. The guadipyr-containing flowable concentrate for seed coating can be used for controlling crop diseases and/or insect pests. The flowable concentrate for seed coating is prepared by compounding the guadipyr with other active components; the prepared product has a higher systemic property and has multiple effects of contact toxicity, stomach toxicity and systemic property, thus being better in control effects.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, and in particular relates to a suspension seed coating agent containing pentetamicloguanidine, a preparation method and application thereof. Background technique [0002] Pentetamiguanidine, chemical name 1-nitro-3-[(6-chloropyridin-3-yl)methyl]-4-pentamethylene aminoguanidine, belongs to nitro aminoguanidine compounds, is a kind of A new insecticide with high efficiency, low toxicity, and low residue, which has both the structural characteristics of neonicotinoid insecticides and sodium ion channel inhibitor insecticides, and thus also has the insecticidal spectrum of these two types of insecticides , has a wide range of applications, and has the characteristics of multiple targets, which will greatly reduce the speed of pest resistance. The product has a good control effect on aphids, planthoppers, cotton bollworms and other piercing-sucking mouthparts pests. [0003] Imidacloprid, chemi...
