Problems solved by technology

[0007] Using the rice safener isoxaprop-ethyl after emergence can increase the resistance of rice to fenoxaprop-p-ethyl, but weeds such as weedy rice and other weeds are less resistant to fenoxaprop-p-ethyl after being exposed to the safener. Drug resistance has also increased; using the rice safener isoxadifen ethyl to treat the seeds can prevent weedy rice and other weeds from contacting the safener. However, isoxadifen ethyl is not easy to absorb and cannot effectively protect Rice protected from phytotoxicity
Seed treatment with isoxazole carboxylic acid can play a protective role, but it can inhibit the emergence rate of rice

Abstract

The invention relates to a rice seed treatment agent, which comprises effective components and auxiliary agents, wherein the mass of the effective components accounts for 5-85% of the total mass of the rice seed treatment agent, the effective components are isoxadifen and gibberellin, and the auxiliary agents comprise three or more than three materials selected from a surfactant, a solvent, a suspending auxiliary agent and an anti-freezing agent. According to the present invention, the rice seed treatment agent can treat rice seeds, can improve the drug resistance on fenoxaprop-P-ethyl and other herbicides at the rice seedling stage, can improve the selectivity between rice and other malicious weeds such as weedy rice and the like of herbicides, can ensure the seedling emergence rate of rice, and can reduce the influence on the germination rate of rice seeds during the single treatment with isoxadifen.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a rice seed treatment agent. Background technique [0002] Rice is one of the most important food crops in the world. There are serious weeds in paddy fields, among which gramineous weeds are difficult to control. Efficient, safe and selective herbicides for gramineous weeds in paddy fields have broad market prospects and commercial value. [0003] Fenoxaprop-ethyl has a high control effect on gramineous weeds, but it is less safe for rice when used in the seedling stage of rice, and it is prone to phytotoxicity when rice seedlings are young in seedling fields or direct-seeding rice fields. [0004] Ethyl isoxadifen, English name: isoxadifen-ethyl, CAS number: 163520-33-0, molecular formula: C 18 h 17 NO 3 , chemical name: ethyl 4,5-dihydro-5,5-diphenyl-1,2-azole-3-carboxylate, is a safener, commonly used to improve the resistance of corn to herbicides. The safener has str...
