Abstract
The invention discloses a phytocidal composite used for cotton crop, which contains the following components: (A) pyrithiobac-sodium (2-chlorin-6 (4, 6-dimethoxy pyrimidine-2-gluthione) sodium benzoate), (B) any of the following weedicides: quizalofop-p-ethyl, high-efficiency haloxyfop, fluazifop-p-butyl, fenoxaprop, sethoxydim or clethodim, (C) addition agent for the rest; wherein, the weight ratio of the component (A) and the component (B) is 1:20 to 20:1. The phytocidal composite efficiently expands the weed control spectrum and has better control efficiency to the main grassy weed and the broadleaves in the cotton field.
Description
Technical field
The invention belongs to the pesticide herbicide field, especially a kind of Herbicidal combinations that is used for cotton crop.
Background technology
Cotton is China's main economic crops, and effectively controlling the cotton field weed is one of important measures that improve output of cotton and quality.The survey showed that according to cotton field weed pests occurrence rule, and the cotton field weeds is taken place is mainly broad leaved weeds such as lamb's-quarters, Amaranthus retroflexus, kitchen garden, acalypha copperleaf, and it accounts for weeds about 70% of total amount takes place.Produce the weed killer herbicide of going up control cotton field weed at present and be mainly processing soil treatment agents such as Acetochlor, pendimethalin, trefanocide, Jin Douer, it mainly prevents and treats grassy weed and part broad leaved weed, all can be effectively cotton Tanaka's lady's-grass, eleusine indica, barnyard grass grass etc. be prevented and kill off, but relatively poor to preventive effects such as cotton field main weeds lamb's-quarters, kitchen garden, acalypha copperleafs.In addition, processing soil treatment agent is had relatively high expectations to soil moisture, the North China of one of cotton main producing region is generally at sowing cotton in the first tenday period of a month in May every year, north arid is short of rain at a time when this, cause cotton field processing soil treatment agent drug effect to reduce and the lasting period weak point, medicament has comparatively serious poisoning to cotton seedling simultaneously, shows as leaf malformation, and plant strain growth is suppressed.
The cauline leaf inorganic agent is compared with processing soil treatment agent, and it has, and environmental pollution is little, consumption is few, require advantage such as low to become the main weed killer herbicide type of promoting in the present production to soil moisture, is just having the cauline leaf inorganic agent to replace the trend of processing soil treatment agent at present abroad.
By above-mentioned analysis as can be seen, the cotton field weed is based on broad leaved weed at present, but the weed killer herbicide kind of promoting in the production is is mainly prevented and treated grassy weed and is processing soil treatment agent, and does not also have the effectively cauline leaf inorganic agent of control cotton field broad leaved weed of registration at home.In such cases, the exploitation effectively foliar herbicide kind of control cotton field grass family and broad leaved weed will become one of main task of following pesticidal preparations worker.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Herbicidal combinations that is used for cotton crop that can prevent and kill off grassy weed and broad leaved weed.
For solving the problems of the technologies described above, the present composition contains:
(A) pyrithiobac-sodium (2-chloro-6-(4,6-dimethoxypyridin-2-base sulphur) Sodium Benzoate),
(B) be selected from following any one weed killer herbicide: Quizalotop-ethyl, efficient haloxyfop-methyl spirit, efficient fluazifop, fenoxaprop, sethoxydim or clethodim,
(C) surplus auxiliary agent;
Wherein component (A) is 1:20～20:1 with the weight ratio of component (B).
For further solving the problems of the technologies described above, the weight fraction of component in the present composition (A)+(B) in composition is preferably 5-70%.
When the present composition was made Wettable Powder and water dispersible granules, auxiliary agent (C) preferably was grouped into by the one-tenth of following weight mark: wetting agent 1-3%, dispersant 2-5% and solid carrier 22-92%
When the present composition was made oil-suspending agent, auxiliary agent (C) preferably was grouped into by the one-tenth of following weight mark: emulsifier 3-5%, antifreezing agent 1-5%, stabilizing agent 1-5%, defoamer 1-5% and organic solvent 10-89%.
When the present composition was made emulsifiable concentrate, auxiliary agent (C) preferably was grouped into by the one-tenth of following weight mark: emulsifier 3-25% and organic solvent 10-89%.
Adopt the beneficial effect that technique scheme produced to be: the grassy weed that composition of the present invention mainly takes place the cotton field is closed broad leaved weed all preventive effect preferably, compares with each single agent, has enlarged to kill the grass spectrum.

According to the pesticide field efficacy medicine test criterion of The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC's regulation, every sub-district area is established 20m
2, arrange each sub-district district's group at random, and every chemicals treatment repeats 4 times.
When treating that the cotton field weed grows to the 2-4 leaf, each medicament sprays by each dosage in the table 1, and spouting liquid is 600 liters/hectare.The spray medicine is after 30 days, and the various weeds acrial part of clip weighing fresh weight calculates the fresh weight preventive effect of each medicament to weeds according to formula (1).
4, result of the test:
Table 1, different reagent agent are to cotton field weed preventive effect
As can be seen from Table 1, any one the composition that is mixed of the present invention is compared with weed killer herbicide list agent such as pyrithiobac-sodium, Quizalotop-ethyl, efficient haloxyfop-methyl spirit, efficient fluazifop, fenoxaprop, sethoxydim, clethodims, effectively enlarged and killed the grass spectrum, cotton Tanaka's main grassy weed and broad leaved weed all had preventive effect preferably.When any one weight ratio of 6 kinds of weed killer herbicides such as pyrithiobac-sodium and Quizalotop-ethyl, efficient haloxyfop-methyl spirit, efficient fluazifop, fenoxaprop, sethoxydim, clethodim is 1:3～3:1, best to the preventive effect of various weeds.
