Abstract

The invention relates to a cyprodinil and iprovalicarb containing sterilizing composition and application thereof. The composition contains cyprodinil and iprovalicarb in weight ratio of (1-40) to (1-45). The composition can be used for preventing and treating disease damage of industrial crops, food grains or flowers and other plants. The composition is wide in applicable scope, good in effect, low in cost, and safe to a human body, livestock and environment, and few residues exist.

Description

technical field [0001] The invention relates to a fungicidal composition and its application, in particular to a fungicidal composition containing cyprodinil and valitecarb and its application, which is mainly used for the prevention and treatment of economic crop diseases. Background technique [0002] Cyprodinil (Cyprodinil, CAS No. 121552-61-2) is a methionine biosynthesis inhibitor that has no cross-resistance with triazoles, imidazoles, morpholines, phenylpyrroles, etc. , leaf penetration and root systemic activity. Foliar spray or seed treatment can also be used as barley seed coating agent. [0003] Carbamic acid (Carbamic acid, CAS No. 140923-17-7) is an amino acid ester derivative with a unique new biomimetic structure that makes its mechanism of action different from other fungicides for the control of oomycetes. Its mechanism of action is to act on the synthesis of fungal cell walls and proteins, inhibit the infection and germination of spores, and at the same t...
