Embodiment 1

[0020] Example 1: 60% Bispyribac-Tamifluzed Wettable Powder (Bisfluben:Tamifluzed = 1:4)

[0021] Take 12kg of bispyribac, 48kg of trifenil, 4kg of dispersant NNO, 3kg of wetting agent K12, 4kg of white carbon black, 0.08kg of diethylaminoethanol hexanoate, and light calcium carbonate to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 2

[0022] Example 2: 28% bispyribac-tamifluzed emulsifiable concentrate (bisfluben: triacamid = 1:6)

[0023] Take 4kg of bispyribac, 24kg of trifenazole, 10kg of emulsifier, and make up to 100kg of solvent. After fully mixing and preparing, an emulsifiable cream is obtained.

Embodiment 3

[0024] Example 3: 18% bispyribac-triamfac dispersible oil suspension concentrate (bisfluorin: trifenil = 1:8)

[0025] Take 2kg of bispyribac, 16kg of trifenac, 8kg of Pluronic125 (polyoxyethylene polyoxypropylene block copolymer), 0.01kg of diethylaminoethanol hexanoate, and methylated vegetable oil to make up to 100kg. The oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Abstract

The invention provides post-emergence herbicide containing bispyribac-sodium and ipfencarbazone used for rice. The post-emergence herbicide is characterized in that active ingredients of the post-emergence herbicide composition comprise bispyribac-sodium and ipfencarbazone in the weight ratio being 1: (0.1-80). The compound herbicide can control annual gramineous weeds such as caper euphorbia seeds, barnyard grass and the like as well as cyperaceous weeds and broadleaf weeds in a rice field, has a prominent synergism effect, has no influence on succeeding crops and is ideal.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a post-emergence herbicide for rice containing bispyribac and trifenazole. 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 feeds on rice. The planting area and output of rice rank first in my country's food crops, and its production covers all continents except Antarctica. more than half. There have always been a large number of weeds in rice fields in all rice-growing areas in my country, among which the area of ​​moderate weed damage accounts for more than 46% of the total planting area, and the area of ​​severe damage is more than 11.5%, resulting in an annual grain loss of more than 20 billion kilograms . Therefore, in order to increase the rice yield, the use ratio of domestic rice field herbicides is almost 100%, and its dosage is very large...
