Problems solved by technology

The current method of controlling weeds in farmland is mainly spraying herbicides. A single type of herbicide has a narrow herbicidal spectrum, while a multi-component herbicidal composition can expand the herbicidal spectrum.
[0003] Metrazil is a new type of carbamoyl tetrazolinone herbicide created and developed by Bayer Corporation of Japan. In actual application, Metrazen has a faster weeding speed and can inhibit the growth of weeds after application. It has excellent control effect on gramineous weeds and sedge weeds in paddy fields, but the herbicide is only effective on some broad-leaved weeds, and has poor effect on Polygonum lilac, Echinochloa chinensis, Cyperus chinensis and Alisma weeds , cannot completely control broadleaf weeds in rice fields
[0004] Fluroxypyr is a systemic conduction type post-emergence herbicide, which is quickly absorbed by plant leaves and roots after application, and is quickly transmitted in the body. It has the effect of plant hormones, has strong lethality to plants, and the dosage per unit area is small , Fluroxypyr can control a variety of broadleaf weeds, but it is ineffective against gramineous weeds
[0005] Metrazen and fluroxyfen are both single-class herbicides, both of which have the problems of too narrow herbicidal spectrum and slow weeding speed, and the drug effect is not very ideal

Abstract

The invention relates to the field of pesticide herbicides, and particularly discloses a weeding composite containing fentrazamide and fluroxypyr. The weeding composite containing fentrazamide and fluroxypyr comprises the effective components of fentrazamide and fluroxypyr in a weight ratio of 1:88 to 88:1. The weeding composite containing fentrazamide and fluroxypyr has the benefits that firstly, the herbicide controlling spectrum is wide: the weeding composite is suitable for prevention and treatment of various annual and perennial weeds, and one-time herbicide application can effectively control the weed harm of the whole growing period of paddy fields; secondly the weeding composite is safe to rice and afterreap crops: even though the usage amount per mu is five times of proposed usage amount, the pesticide hazard is prevented, so that the herbicide application cost is reduced, and the affect on the afterreap crops is also reduced; thirdly, the antagonistic effect is prevented: the weeding composite has synergistic effect on the herbicidal activity of the weeds, and the weed control synergistic effect is remarkable; and fourthly, the cost is low, and the use is convenient.

Description

(1) Technical field [0001] The invention relates to the field of pesticides and herbicides, in particular to a herbicidal composition containing tetramen and fluroxyfen. (2) Background technology [0002] Weeds are an important part of the agricultural ecosystem, and they always compete with crops for glory, fertilizer and water, and are one of the important factors leading to crop growth and yield reduction. In recent years, with the changes in cultivation systems, fertilization and sowing methods, weed damage in paddy fields has become very prominent, causing great losses to crop production every year. In addition, weed communities and dominant populations have also changed. Brome bistica, Sagittarius japonica, Echinacea chinensis, Columba chinensis, Polygonum cloves have risen to dominant populations, and some have become vicious weeds. In order to reduce the loss of crops and increase the average annual yield of paddy fields, it is necessary to quickly and effectively c...
