Pesticide composition, and preparation method and application thereof

Abstract

The invention relates to the technical field of agricultural pesticides, specifically to a pesticide composition, and a preparation method and an application thereof. The pesticide is composed of a mixed pesticide and an auxiliary agent, wherein the volume ratio of the mixed pesticide to the auxiliary agent is (2-4): (1-3). The pesticide composition is used for preventing and treating flea beetles, stem weevils, nitidulid, evergestis extimalis scopoli, plutella xylostella, aphids and cabbage caterpillars. The pesticide composition is used by seed dressing and / or spraying. The pesticide composition provided by the invention has the following advantages: (1) the pesticide composition can be used by seed dressing or can be sprayed after being diluted, so the pesticidal spectrum is broadened;(2) the pesticide composition has good synergistic effect, can reduce the usage amount of effective components, reduces the cost of use, and delays the generation of pesticide resistance of pests; (3)the use is safe, and environmental pollution and pesticide residues are effectively reduced; (4) the pesticide composition is flexible and simple in use mode, reduces the cost of production and use,and reduces the pesticide residues and environmental pollution; and (5) the pesticide composition has simple preparation process and is applicable to large-area popularization and application.

Description

technical field

[0001] The invention relates to the technical field of agricultural pesticides, in particular to a pesticide composition, a preparation method of the pesticide composition and an application thereof. Background technique

[0002] In the process of agricultural pest control, different pesticide formulations and types of pesticides are required due to different control objects, control periods, and application methods. For example, for Lepidoptera larvae, wettable powder, emulsifiable concentrate, suspending agent, etc. can be used. Spray control; for underground pests, granules, seed coatings, etc. can be used.

[0003] In the whole growth cycle of spring rapeseed, different types of pests occur in different growth stages, such as: flea beetle at the seedling stage, stem weevil at the stalk stage, weevil beetle at the flowering stage, fennel and fennel borer at the silique stage, and the whole Plutella xylostella, aphids, cabbage caterpillars, etc. that cause...
