Additionally, in same rice field different types of weeds, such as grassy weed, broad leaved weed, dried tuber Mixed raw.Owing to the herbicidal spectrum of active component single in Herbicidal mixture has limitation so that single-activity composition Herbicidal mixtures possibly cannot remove all of weeds in dispenser target rice field.
Sulfonylurea herbicide is selectivity inner-adsorption conduction-type herbicide, can be absorbed by weeds root and blade, Conduct rapidly in plant body, suppression cell division and growth.After susceptible weeds absorbs sulfonylurea herbicide, Plumelet and root stop growing rapidly, and tender tissue turns to be yellow, the most withered.But sulfonylurea herbicide is in application Present in process, a difficult problem is it to the toxicity of favourable plant and weeds to sulfonylurea herbicide drug resistance Development.
It is therefore desirable to research and develop the herbicidal composition of a kind of improvement, especially it is able to control current known group Compound and preparation are difficult to multiple weeds or certain the class weeds prevented and treated.Can disposably or point be applied to crop several times The compositions in particularly rice field, field is useful.
Promazine Sulfometuron Methyl (Propyrisulfuron) is by SUMITOMO CHEMICAL chemistry (Sumitomo Chemical) exploitation Known pyrimidine radicals sulfonylurea herbicide, be mainly used in prevention and control grassy weed (such as barnyard grass) And broad leaved weed, can be widely used for rice field.Although the consumption of required promazine Sulfometuron Methyl is low, it can be very effectively Prevention and the control weeds to sulfonylurea herbicide being produced known to some drug resistance.
