Description
Technical field
It is by effective component rimsulfuron, metribuzin He Evil the present invention relates to compound pesticide combination and its application technology
Oxalic acid is combined, applied to preventing and kill off potato fields weeds.
Background technique
Rimsulfuron, sulfonylurea amino acid compound inhibitor are absorbed by root, stem, leaf, conduct to separate living tissue, pass through
Inhibit the biosynthesis of necessary valine and isoleucine to make cell differentiation and plant growth stop.
Metribuzin, triazines inhibitor of photosynthesis are absorbed by weeds root system and are conducted with transpiration current to top, can also be by leaf
Piece absorption is conducted in vivo.The main photosynthesis by inhibiting sensitive plant plays removing activity, each susceptible weeds after application
Unaffected, rear blade chlorisis of emerging of emerging is sprouted, last nutrition is exhausted and dead.
Evil oxalic acid also known as propaquizafop, phenoxy carboxylic acid fatty acid synthetic inhibitor are absorbed by weeds stem, leaf, in plant
Internal Bidirectional Conduction up and down, is accumulated in top and intercalary meristem, inhibits cell fatty acid synthesis, keeps weeds bad
Extremely.
Chemical method weeding is one of the main means of potato fields control weeds, has efficient, time and labour saving advantage.Horse
Grass phase is complicated for the generation of bell potato field weed, and the mixed life of gramineae weed, broadleaf weeds polymorphic type weeds uses single kind compound
Herbicide is all shown defects and limitations in one aspect, and cannot be fully solved potato fields weed problem.Meanwhile weeding
Agent kind is used alone, and weeds is easy to cause to develop drug resistance.
The present inventor has made intensive studies the combination and its application of rimsulfuron, metribuzin He Evil oxalic acid, a large amount of
The test such as indoor toxicity test, Recipe and crop field drug effect on the basis of, discovery metribuzin He Evil oxalic acid in certain ratio
It is combined in example range, there is notable synergistic effect, improve using effect, expand prevention spectrum, it is miscellaneous to be suitable for potato fields
Grass prevention and treatment.After further study, the present invention is completed.
Summary of the invention
It is an object of the invention to improve Pesticide use effect, expand prevention spectrum, a kind of containing for synergistic function is provided
Have rimsulfuron and metribuzin Yi Ji Evil oxalic acid Herbicidal combinations.
To achieve the above object, technical solution of the present invention：It is a kind of containing rimsulfuron and metribuzin Yi Ji Evil oxalic acid removes
