Problems solved by technology

[0003] However, due to the long-term use of a certain type of herbicide in paddy fields, changes in the farming system of wheat fields, and the introduction of new varieties, the weed community has undergone significant changes. Weeds in paddy fields spread rapidly and continue to spread, and some herbicides have been used. Resistance was found, especially to sulfonylurea herbicides
However, broad-leaved weeds such as Sagittarius japonica, Alisma, Cormina, and Yujiuhua have strong reproductive ability, fast diff

Abstract

The invention relates to the field of pesticide preparations, and discloses a rice field weeding composite and a preparation thereof. The weeding composite is prepared from sulphonamide compound pyrimisulfan and a sulfonylurea compound with a ratio weight of 1:10-20:1. According to the rice field weeding composite and the preparation thereof, the sulphonamide compound pyrimisulfan and the sulfonylurea compound are compounded to serve as an active ingredient; the sulphonamide compound pyrimisulfan and the sulfonylurea compound, which complement each other in advantages and synergistically act, can be used for slowing the generation of herbicide resistance of weeds and meanwhile has a synergistic effect on rice field weeding; the use amount and the number of use times of the herbicide are reduced greatly, so that the composite and the preparation thereof have the advantages of safety, high efficiency, environment friendliness and the like and can be widely used for preventing and controlling rice field weeds.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a paddy field herbicidal composition and its preparation. Background technique [0002] Rice is an annual gramineous plant, which is produced on all continents except Antarctica. Rice is not only the most important food crop in my country, but also one of the main food crops in the world. The world's rice cultivation area is about 145 million hectares. The sown area of ​​rice in my country accounts for 1 / 4 of the country's grain crops. Regardless of planting area or output, rice ranks first among food crops in my country. However, rice fields in all rice-growing regions in my country have suffered from weed damage to varying degrees. Among them, the area of ​​moderate weed damage accounts for more than 46% of the total planting area of ​​rice, and the area of ​​severe weed damage accounts for more than 11.5%. These weeds compete with rice in various aspects and cause dama...
