Abstract
The invention relates to a herbicidal composition, and particularly relates to a herbicidal composition comprising propyrisulfuron and pretilachlor, and an application thereof and a corresponding weed control method. The herbicidal composition comprises active components of propyrisulfuron and pretilachlor, wherein a weight ratio of propyrisulfuron to pretilachloris 100 : 1-1 : 100. The herbicidal composition also can comprise a safety agent and is used for controlling grassy weeds, broad leaf weeds and cyperaceae weeds in the rice fields in crop growth environment. Compared with an individually used herbicide, the herbicidal composition compounded by the propyrisulfuron and pretilachlor enlarges herbicidal spectrum and significantly enhances a weed control effect because propyrisulfuron has control capability for weeds having resistance to known sulfonylurea herbicides and binary compound of the two herbicides allows the herbicidal composition to have an enhanced effect.
Description
Technical field
What the present invention relates to is a kind of Herbicidal combinations, relates in particular to a kind of Herbicidal combinations that contains promazine Sulfometuron Methyl and the third careless amine and uses thereof and corresponding weed control method.
Background technology
At present, in order to promote the growth quality of crop, constantly be devoted to develop the herbicidal effect height in the industry, have the weed killer herbicide that kills careless spectrum, low toxicity, low-residual, crop-selective excellence widely.In the production environment of crop, use some weed killer herbicide can cause some weeds that corresponding medicine is produced certain resistance for a long time.Up to now, many kinds of sulfonyl urea compounds have been actually used in the rice field, and widely used usually is the composite preparation form, contain two or more active components in the preparation and reach for preventing the effective grassy weed kill agent miscellaneous of grassy weed.But in recent years, the weeds of resistance occur sulfonylurea herbicide (for example bensulfuron-methyl, third careless amine and the flazasulfuron) is had, their control has become problem.
Especially can grow in the rice crops influences the important monocotyledon weed of economic benefit in a large number, for example mainly is barnyard grass grass, ischaemum or moleplant seed, uses at present known a kind of rice crops weed killer herbicide or its combination can not obtain satisfied control effect.From global rice culture system, also find noxious plant in addition: belong to as arrowhead genus, pin Lin, for example scouring rush's shape water chestnut, Herba Cyperi Glomerati, firefly Lin and other noxious plant, they mainly are rudiments in the perennial tissue from soil, so than the more difficult control of the weeds of seed germination, and be not easy to control best broad leaved weed kind in the whole weeds spectrum.And resistant weed kind incidence increases (comprising that Herba Cyperi Glomerati belongs to or pin Lin belongs to), uses single-activity component or common combinations can not control these weeds even this makes.
Sulfonylurea herbicide is selectivity inner sucting conduction type weed killer herbicide, is easily absorbed by the root of plant, leaf, and in xylem and phloem conduction, it can suppress the activity of vital acetolactate synthestase (ALS) in the plant corpus.Still there are some difficult problems in sulfonylurea herbicide in application process, wherein the most outstanding is that its residual key and weeds are to the pesticide resistance problem of sulfonylurea herbicide.
Conventional control method for weed is to add effectively to prevent and treat the active component that sulfonylurea herbicide is had the weeds of resistance in existing preparation, thereby has increased the active component number that is used for the combination agent of weeds.In this case, such weed killer herbicide need be arranged, they have gratifying effect for the weeds of anti-sulfonylurea herbicide, and can reduce the amount of active component in the composition.
Promazine Sulfometuron Methyl (Propyrisulfuron) is by the pyrimidine radicals sulfonylurea herbicide of SUMITOMO CHEMICAL chemistry exploitation, is mainly used in paddy field and prevents and kill off grass family and broad leaved weeds such as barnyard grass grass.This product consumption is low, and the weeds that some known sulfonylurea herbicide produced resistance have good preventive effect.
