Embodiment 1

[0019] Example 1: 20% Cyhalofop-Trimazole Emulsible Concentrate (Cyhalofop-methyl:Tamifluzed = 1:1)

[0020] 10kg of cyhalofop-ethyl, 10kg of trifenazole, and xylene were supplemented to 100kg to obtain an emulsifiable concentrate.

Embodiment 2

[0021] Example 2: 48% Cyhalofop-Trimazole wettable powder (Cyhalofop-methyl: Triclofenac = 1:2)

[0022] Take 16kg of cyhalofop-ethyl, 32kg of trifenazole, 4kg of dispersant NNO, 3kg of wetting agent K12, 4kg of white carbon black, and light calcium carbonate to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 3

[0023] Example 3: 24% Cyhalofop-Trimazole-Tamifluzed Dispersible Oil Suspension Concentrate (Cyhalofop-methyl: Triclofenac = 1:3)

[0024] Take 6kg of cyhalofop-ethyl, 18kg of trifenazole, 8kg of Pluronic125, 5kg of propylene glycol, 0.5kg of xanthan gum, 1kg of methylated vegetable oil, and make up to 100kg of water. The oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Abstract

The invention discloses a disposable compound post-emergence herbicide for rice. The herbicide consists of active ingredients, namely cyhalofop-butyl and ipfencarbazone, wherein the weight ratio of cyhalofop-butyl to ipfencarbazone is 1:(1-5). According to the compound herbicide, annual gramineous weeds such as leptochloa chinensis and barnyard grass in a rice field can be prevented and controlled, cyperaceous weeds and part of broadleaf weeds can also be prevented and controlled, remarkable herbicidal effects are achieved, remarkable synergistic effects particularly on leptochloa chinensis and cyperaceous weeds are also achieved, influence on succession crops is eliminated, the using amount per mu is reduced, the agricultural cost is greatly reduced, and the herbicide is ideal.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a one-time post-emergence compound herbicide for rice. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including nearly the entire population of East and Southeast Asia, eat rice, which is grown on every continent except Antarctica. In the late last century, the average annual rice output in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. my country's rice planting area accounts for 1 / 4 of the country's grain crops, about 35 million hectares per year, and the output accounts for more than half of the total grain crops. Therefore, regardless of the planting area and output, rice ranks first in my country's food crops. There have always been a large number of weeds in rice fields in all rice-growin...
