Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention provides a paddy field herbicide. The paddy field herbicide comprises the following active ingredients in parts by weight: 1-10 parts of pyrazosulfuron, 1-20 parts of cyhalofop-butyl and 1-15 parts of quinclorac, wherein the active ingredients account for 50-95% by weight of the herbicide; the herbicide further comprises a functional auxiliary; and the functional auxiliary is one selected from a solvent, a dispersing agent, a penetrating agent, a wetting agent, a stabilizer, a defoaming agent and an anti-freezing agent.

Description

Technical field [0001] The invention belongs to the field of chemical pesticides, and specifically relates to a herbicide for weeding in paddy fields. Background technique [0002] There are mainly the following types of weeds in paddy fields: ①Grass weeds: mainly barnyardgrass, crabgrass, goosegrass, etc.; ②Cyperaceae weeds: mainly cyperus rotundus, cardamine sedge, water centipede, etc.; ③ Broadleaf weeds: mainly Alternanthera philoxeroides and Pterocephalus sibiricum. Among them, gramineous weeds and Cyperaceae weeds are collectively called monocotyledonous weeds. Broadleaf weeds are also called dicotyledonous weeds. Gramineous weeds include: Barnyardgrass, Stephanotis, Paspalum biflora, Crabgrass, Setaria, Gooseweed, Dew grass, Wild oats, etc. Cyperaceae weeds include: alien sedges, flat stalks of sedge grass, water sedges, sun fluttering grass, cow felt, cardamine sedge, wild water chestnuts, etc. Broad-leaved weeds include: Pondweed, duck tongue, Moshangcai, Jiejiecai, ...
