Problems solved by technology

However, herbicides are a double-edged sword. During the use of herbicides, due to their own characteristics, processing quality problems, irregular use, and poor environmental conditions, they will cause phytotoxicity to crops.
Crop injury caused by herbicides occurs frequently, large-scale injury occurs from time to time, and food loss is serious
[0003] Bispyribac, Penoxsulam, Fenoxaprop-P-P, Fenoxam, Cyhalofen, quinclorac, isooctyl fluroxypyr, sodium 2-methyl-4-chloride, triclosan Ammonium, butachlor, clomazone, pyrazosulfuron-methyl, and bensulfuron-methyl are commonly used herbicides in rice fields, however, not all of these active ingredients are fully compatible with rice, so they have certain effects in crops. It should be used at a certain dose during the growth period, and the detoxification effect of the climate and rice field moisture cannot be guaranteed.

Embodiment 1

[0018] Example 1: 6% cloxacloxazole·isoxadifen suspension concentrate and its preparation method.

[0019] 1% fenoxazole, 5% isoxadifen, 4% Nongru 1601#, 2% sodium tea sulfonate, 3% magnesium aluminum silicate, 2% ethylene glycol, 2% benzoic acid, 1.5% organic Silicon defoamer, 1.5% epichlorohydrin, and deionized water are added to 100% by weight. The specific production steps are: mixing the active ingredients and other additives, dispersing by high-speed shearing, and sanding in a sand mill to form a highly dispersed and stable suspension system in an aqueous medium to obtain 6% oxacloxazole. Isoxadifen suspension concentrate.

Embodiment 2

[0020] Example 2: 20% bispyribac ether dispersible oil suspension concentrate and its preparation method

[0021] 20% bispyribac, 5% fenoxazole, 5% isoxadifen, 3% sodium lignosulfonate, 5% Nongru 700#, 4% BY-110, 2% sodium naphthalenesulfonate, 1.5 % bentonite, 3% propylene glycol, wheat oil added to 100% parts by weight. The specific production steps are: mixing the active ingredients and other additives, dispersing by high-speed shearing, sanding in a sand mill, forming a highly dispersed and stable suspension system in an oil-based medium, and preparing 26% bispyribac. Dispersible Oil Suspension Concentrate of Methoxazole·Bisoxadifen.

Embodiment 3

[0022] Example 3: 60% fenoxazole·isoxadifen water dispersible granule and its preparation method

[0023] 50% fenoxazole, 10% isoxadifen, 3% GY-D06, 4% sodium lignosulfonate, 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 4% K-12 (Sodium Lauryl Sulfate), Light Calcium is added to 100% parts by weight. The above-mentioned raw materials are conventionally prepared and mixed with ultra-fine airflow, pulverized and granulated to obtain 60% fenoxazole·isoxadifen water-dispersible granules.

Abstract

The invention relates to a safener for rice herbicide. The active ingredient of the safener is prepared from isoxadifen-ethyl and furilazole. The weight ratio of the isoxadifen-ethyl to the furilazolein the rice herbicide is 1: 30-30:1. The safener significantly improves the adverse effect of rice herbicide resistance, enhances the effect of rice herbicide tolerance, and a purpose of safe and efficient weed control is achieved.

Description

technical field [0001] The invention relates to the field of biotechnology, and relates to a safener composition, which enhances rice resistance to herbicide damage and improves the safety of herbicides on rice. Background technique [0002] Herbicides play a huge role in protecting crops from weeds, promoting crop growth, and improving the quality and quality of agricultural products. They have rapidly developed into an important means of agricultural weeding and have been rapidly popularized and applied in production. However, herbicides are a double-edged sword. During the use of herbicides, due to their own characteristics, processing quality problems, irregular use, and poor environmental conditions, they will cause phytotoxicity to crops. The crop phytotoxicity caused by herbicide occurs frequently, large-scale phytotoxicity occurs from time to time, and the grain loss is serious.
