Abstract
The invention discloses a pesticide composition prepared by using bromothalonil and prochloraz. The composition is characterized in that a mass ratio of bromothalonil to prochloraz is 50:1-1:50. A mass ratio of bromothalonil to prochloraz is 3:1-1:1. The composition integrating the performances of bromothalonil and the performances of prochloraz can be used for controlling the anthracnose, powdery mildew and scab of vegetables and fruit trees, and the fruit storage diseases.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specifically related to a kind of composition pesticide of preparing with bromothalonil and Prochloraz.
Background technology
Bromothalonil, as a kind of wide spectrum, low toxicity, mildew-resistant, algae-killing bactericidal agent, has good control efficiency to corps diseases, especially anthracnose is had to special efficacy.But bromothalonil registration in the market seldom, only has two kinds of 25% bromothalonil missible oil (wetting powder) and the bromothalonil of good fortune more than 40% wetting powders.
Prochloraz is a kind of imidazoles broad-spectrum germicide.The various crop disease causing for sac fungi and imperfect fungus has special efficacy.By suppressing the biosynthesis of sterol, cause effect.Although do not have a systemic action, it has certain conductive performance.On market, registered product is more, but take single dose as main, and part built agent is all composite with conventional ingredient, lacks innovation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of composition pesticide of preparing with bromothalonil and Prochloraz, and the performance of comprehensive bromothalonil and Prochloraz, for preventing and treating anthracnose, powdery mildew, scab and the fruit storage disease of vegetables and fruit tree.
