Problems solved by technology

However, when using Fenoxaprop-P-P for weeding in paddy fields, due to reasons such as soil moisture in paddy fields, rice varieties, pesticide application equipment, unreasonable mixing and unfavorable meteorological factors not controlled by humans, Fenoxaprop-P-P is effective against Incidents of phytotoxicity in rice occur from time to time
[0004] In terms of research on detoxification of herbicide damage, the currently implemented methods are: washing with water, applying seedling fertilizer early, topdressing quick-acting fertilizer, strengthening intertillage loosening, spraying plant growth regulators, applying promoting regulators, spraying baking soda Alkaline substances such as water, etc., but the above methods can only relieve slight herbicide damage

Embodiment 1

[0042] Example 1 Preparation method of 5% oxaprop-ethyl-ethyl dispersible oil suspension

[0043] Fenoxaprop-P-P-P 5%, Diclofenac 4%, Lecithin 1%, Pull Open Powder BX 2%, Polycarboxylate 5%, Fatty Acid Polyoxyethylene Ester Phosphate 8%, Tween-80#5 %, carboxymethyl cellulose 2%, ethylene glycol 2.5%, and methyl oleate make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 5% fenoxaprop-p-ethyl dispersible oil suspension concentrate.

Embodiment 2

[0044] Example 2 Preparation method of 8% oxaprop-ethyl-ethyl suspension concentrate

[0045] Fenoxaprop-P-P-P 8%, Diclofenac 2%, Lecithin 2%, Lignosulfonate 6%, Nongru 700# 10%, Phenylphenol Polyoxyethylene Ether Phosphate 4%, Acetic Acid 5% sec-butyl ester, 0.2% xanthan gum, 0.5% benzoic acid, 0.5% silicone oil, 2.5% ethylene glycol, deionized water to make up to 100%. The above-mentioned materials were mixed in proportion, and after being uniformly stirred by high-speed shearing, an 8% oxaprop-ethyl-ethyl suspension concentrate was prepared.

Embodiment 3

[0046] Example 3 Preparation method of 10% fenoxaprop-ethyl-ethyl emulsifiable concentrate

[0047] Fenoxaprop-P-P-10%, 10% clofenac, 4% lecithin, 7% rosin-based vegetable oil, 2% phenylethylphenol polyoxypropylene polyoxyethylene ether, 3% calcium dodecylbenzenesulfonate , 2-butyl acetate supplemented to 100 grams. Add the above-mentioned components into the mixing kettle in sequence, and stir evenly to obtain 10% fenoxaprop-ethyl-ethyl emulsifiable concentrate.

Abstract

The invention relates to a fenoxaprop-p-ethyl damage-resistant composition for rice. The composition comprises a herbicide and a safener, wherein the herbicide comprises fenoxaprop-p-ethyl, the safener is a binary combination of fenclorim and lecithin, and the ratio of the herbicide to the safener is (1-10):(1-10). The composition has the effect of resisting fenoxaprop-p-ethyl damage of rice, andthe use effect is improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a safener for alleviating the phytotoxicity of fenoxaprop-ethyl-ethyl to rice. Background technique [0002] With the promotion of no-tillage agriculture, chemical weeding has rapidly developed into an important means of agricultural weeding due to its high efficiency, low toxicity, labor-saving, time-saving, and high return on labor, and has been rapidly popularized and applied in production. [0003] Fenoxaprop-p-ethyl has an excellent effect on controlling barnyardgrass, Qianjinzi, crabgrass and other vicious gramineous weeds in Hunan, Jiangxi, Anhui, Jiangsu and other southern rice areas, and its cost is low. However, when using Fenoxaprop-P-P for weeding in paddy fields, due to reasons such as soil moisture in paddy fields, rice varieties, pesticide application equipment, unreasonable mixing and unfavorable meteorological factors not controlled by humans, Fenoxaprop-P-P i...
