Description

A kind of active compound and weed killer herbicide thereof for weeding in cotton field
Technical field
The present invention relates to a kind of active compound for weeding in cotton field, especially by herbicidal composition and the application thereof of the control Cotton Fields weeds of pyrimidine benzylamine class weed killer herbicide and chloroamides class mixture of herbicides.
Background technology
China is maximum in the world Cotton Production state, and sown areas of cotton and gross yield account for the world 1/4 at present.The used weed killer herbicide of Cotton Fields mainly comprise broadcast before and broadcast processing soil treatment agent and cauline leaf inorganic agent two large classes before the rear seedling.The general cost of cauline leaf inorganic agent medication is higher, so the weeding of Cotton in China field is mainly take processing soil treatment agent as main.Three large Cotton Fields closed soil treatment agent commonly used are Pendimethalin, Acetochlor and trefanocide, and the Pendimethalin use cost is too high; Acetochlor herbicide spectrum is narrow, and the lasting period is short, and soil moisture content is had relatively high expectations; Trefanocide belongs to long residual effect weed killer herbicide, easily causes the poisoning of rear stubble, and must mix soil when using, take a lot of work consuming time, with after can cause that also cotton knee is large.Owing to using for a long time weed killer herbicide aborning, great changes have occured in weed community simultaneously, and in certain areas, what drug resistance was strong becomes to rising.
Therefore need a kind of new weeding in cotton field agent of exploitation, can enlarge the herbicide spectrum, improve preventive effect, delaying drug resistance, reduce cost.
ZJ1835 is by the 2-2-pyrimidinyl oxy of our discovery-N-arylbenzylamines class weed killer herbicide.It may become the efficient Cotton Fields herbicides special of the autonomous initiative of China, have synthesis material and be easy to get, synthesize the characteristics such as simple, simultaneously, have the advantages such as efficient, safety, herbicide spectrum are wider, compare with weeding in cotton field agent in the market and have certain technical advantage.But owing to using for a long time weed killer herbicide, great changes have occured in weed community aborning, and in certain areas, what drug resistance was strong becomes to rising.Therefore, the complex preparation of exploitation ZJ1835 is to enlarge the herbicide spectrum, to improve preventive effect, delaying drug resistance, and reduction cost etc. is to realize the most effective approach of its using value.
Summary of the invention
The object of the present invention is to provide a kind of active compound for weeding in cotton field, can enlarge the herbicide spectrum, improve preventive effect, delaying drug resistance and reduction cost.
For achieving the above object, the invention provides following technical scheme:
A kind of active compound for weeding in cotton field contains N-phenyl shown in the formula (I)-[2-chloro-6-(4,6-dimethoxypyridin-2-oxygen base)] benzylamine and Acetochlor.

Active compound for weeding in cotton field of the present invention is compared with existing weeding in cotton field agent with the weeding in cotton field agent, has the following advantages:
(1) broad weed-killing spectrum, activity of weeding is high
Active ingredient ZJ1835 all has preventive effect to present Cotton Fields main weeds, and excellent to the broad leaved weed preventive effect, the active ingredient Acetochlor is mainly prevented and kill off Cotton Fields grassy weed and part broad leaved weed.Two kinds of combination of active principles produce synergistic function, Effective Raise herbicide spectrum and preventive effect.
(2) crop safety is high
The active ingredient ZJ1835 that the present invention selects and Acetochlor all are efficient or super-high-efficient, low toxicity, eco-friendly weed killer herbicide, and the product after composite shows cotton safety is arranged through lot of experiments and application.Composite by making up, reduced the consumption of ZJ1835 and Acetochlor, avoided the ZJ1835 to the inhibition at cotton growth initial stage, also avoided Acetochlor generation to cotton's medicine harm under hot and humid condition.Herbicidal composition of the present invention is to the cotton safety raising, and to succession crop safety.
(3) without antagonism
Formula indoor screening and the bioassay results of herbicidal composition provided by the present invention show: the combination between any 2 kinds of active ingredients is synergistic effect to the activity of weeding of test weeds, without antagonism.
(4) complementation of action characteristic
The drug effect of active ingredient ZJ1835 performance is insensitive to temp. and humidity among the present invention, and the medium drug effect of temp. and humidity is bringd into play.And Acetochlor belongs to happiness temperature happiness wet type, both composite deficiencies that remedy Acetochlor.
(5) weeds non-resistant
Active ingredient ZJ1835 is novel cotton field herbicidal among the present invention, has alleviated present Cotton Fields weeds to the resistance problem of conventional variety.

Above herbicidal composition is carried out the greenhouse pot culture active determination test, between the comparative composition, and the activity of weeding between composition and the single dose.The result shows: herbicidal composition all shows for the higher preventive effect of examination weeds, compares with single dose, has improved activity of weeding, has accelerated drug effect performance speed, has enlarged the herbicide spectrum, has reduced use cost.
The herbicidal composition formulation screening test carries out according to following method:
Test is the sandy loam of preparation with soil, and the activity of weeding test is 9.5cm with basin alms bowl diameter.
Test was processed before the greenhouse pot culture method was carried out bud.Carry out one day after the soil surface spraying in sowing and process, the liquid of processing is needs dosage for the preparation thin up of each single dose.
After the basin alms bowl of processing leaves standstill 1 day, put into the greenhouse, regularly water, each repetition activity of weeding of ocular estimate observed and recorded compound is averaging activity of weeding after 14～21 days.
With the activity of weeding of hazard of plant symptom (inhibition, deformity, yellow, albefaction) performance degree range estimation compound, 0 expression does not have herbicidal effect or to crop safety, weeds or crop are killed in 100% expression fully.Activity of weeding and crop safety ocular estimate evaluation criterion see Table 1, and the biological activity determination test target of selection sees Table 2.

Composition synergy Types Assessment method is as follows:
The Gowing method is a kind of herbicide mixture synergy Types Assessment method that proposes nineteen sixty.Concrete steps are to measure first single dose and mixture to the preventive effect of target weeds, calculate the theoretical preventive effect of mixture by the actual measurement preventive effect of single dose, again its actual measurement preventive effect with mixture are recently estimated the synergy type mutually.
Theoretical preventive effect computing formula is: E 0=X+Y-XY/100.X, Y are respectively the actual measurement preventive effect value (%) of two single doses in the formula, and E is actual measurement preventive effect value (%), E 0Be theoretical preventive effect value (%).
Activity of weeding the results are shown in Table 3 before ZJ1835 and Acetochlor were used the bud of different proportionings with: the result shows, ZJ1835 and Acetochlor are used actual measurement preventive effect (E) to lady's-grass, green foxtail, Amaranthus retroflexus and kitchen garden with all greater than theoretical preventive effect (E 0).Show that ZJ1835 and Acetochlor use with and just have synergistic effect.
