Abstract
The invention discloses a product for crop protection, which is characterized by taking Tebuconazol as a first active component and chitosan as a second active component, wherein the ratio of the first active component to the second active component is 1:100-100:1 by weight percentage. The invention can improve disease resistance of crops, has good protection function when the crops are in a non-invasive period or an initially-invasive period, and has the advantages of reducing times of medication, improving quality of agricultural products, increasing yield and the like. When being used after invasion, the invention can eradicate etiology, repair impaired parts, protect for a long time, and conforms to the thought of scientific prevention and treatment and requirement of green agriculture production. The invention can be applied widely in prevention and control of various diseases such as powdery mildew, false smut, sheath blight, leaf spot, plague, gray mold disease, root rot disease and fusarium head blight of crops of cereal crops, fruit trees, vegetables, peanuts and the like.
Description
Technical field
The present invention relates to composite composition of a kind of Tebuconazole and chitosan and application thereof, belong to technical field of compounded pesticide.
Background technology
Tebuconazole (English common name: tebuconazole) have another name called the Garrick show, molecular formula: C
