Abstract
The invention relates to three types of haulm weed removal composition for weed control in rape fields, which include fenoxaprop-ethyl and benazolin-ethyl weed removal composition, fenoxaprop-ethyl and clopyralid weed removal composition, fenoxaprop-ethyl and ethametsulfuron weed removal composition. The three kinds of weeding composition provided by the invention can be applied for effectively preventing the eradicating various weeds in the rape filed and sustaining good safety to crops of different stages.
Description
The invention belongs to the agricultural herbicide field.
Along with the development of agricultural cience and farming techniques, chemical herbicide has become one of effective measure of agricultural produce with its saving of work and time, the characteristics of not damaging crops.
China is large agricultural country, and rape is the topmost oil crop of China, because the economic worth height, the enthusiasm of peasant planting rape significantly improves in recent years, and this has positive role to solving the agriculture, rural areas and farmers problem and improving peasant income.
China rape field is subjected to the weeds hazard ratio more serious, and winter rape field, Yangtze river basin crop smothering area reaches more than 3,000 ten thousand mu, and in spring rape producing region, northwest, the crop smothering area is also up to more than 300 ten thousand mu.
Rape field weeding has modes such as artificial weeding and chemical weed control.Artificial weeding is time-consuming, and labour intensity is big, the weed germination rate of being completely cured height, and recurrence is fast.Artificial weeding also can cause certain damage to rape simultaneously.Chemical weed control has overcome the defective of artificial weeding, so obtain rapid penetration and promotion in recent years.
Herbicide used in rape field mainly contains processing soil treatment agent Acetochlor, napropamide, benthiocarb etc., and kinds such as cauline leaf inorganic agent ethametsulfuron, benazolin, Quizalotop-ethyl are arranged.These kinds or owing to influenced greatly by climate, herbicidal effect is poor; Perhaps big owing to consumption, the cost height; Perhaps long owing to the longevity of residure, serious to the succession crop poisoning; Perhaps because herbicidal spectrum is narrow, the total careless preventive effect in field is undesirable, has been subjected to certain limitation thereby make to apply.
The objective of the invention is to seek a kind of novel Herbicidal composition of rape field that can overcome above-mentioned defective, both had the advantage that activity is high, consumption is few, cost is low, have careless wide spectrum, good, the tangible characteristics of synergistic effect of safety of killing again, to remedy the deficiency of rape field weed killer herbicide commonly used.
Fenoxaprop is good foliar herbicide, and grassy weed is had special efficacy, can be widely used in the field weeding of crops such as paddy rice, wheat, rape, soybean.But fatal weakness is invalid to the field broad leaved weed, therefore the harm of all weeds of the uncontrollable field of Shi Yong fenoxaprop separately.
The present invention is by compound (I) fenoxaprop and compound (II) benazolinethyl, or compound (I) fenoxaprop and compound (III) clopyralid, or compound (I) fenoxaprop and compound (IV) ethametsulfuron combination is mixed and realizes.
The structural formula of compound (I), (II), (III), (IV) is as follows:
Compound (I): fenoxaprop
Compound (II): benazolinethyl
Compound (III): clopyralid
Compound (IV): ethametsulfuron
Wherein (part by weight of I) fenoxaprop and compound (II) benazolinethyl is 10 to compound: 1-100;
(part by weight of I) fenoxaprop and compound (III) clopyralid is 10 to compound: 1-50;
(part by weight of I) fenoxaprop and compound (IV) ethametsulfuron is 10 to compound: 0.1-10.
Advantage of the present invention is that significantly it mainly shows:
1, cauline leaf of the present invention is handled Herbicidal combinations, no any antagonism between each composition, and synergistic effect is remarkable.
2, to be key component be processed into various formulations according to various formulations of pesticide processing methods carries out field weeding when using with two kinds of compounds according to the present invention, and the one, the agent of amount ratio list is used and is significantly reduced, and has reduced cost, can reduce farmer's burdens; The 2nd, to use conveniently than existing mixing now, drug effect is better.
3, Herbicidal combinations of the present invention compares with using single effective ingredient separately, has enlarged to kill the grass spectrum, and a weeding can be saved from damage season, and herbicidal effect is better.
4, Herbicidal combinations of the present invention belongs to cauline leaf and handles weed killer herbicide, sees grass back dispenser, and medicine removes to grass, has overcome the blindly defective of dispenser of soil processing herbicide, can be the peasant and reduces unnecessary medication expenditure.
5, Herbicidal combinations low toxicity of the present invention to people, animal, birds and beneficial organism safety, helps environmental protection and keeps ecological balance.
6, the production technology of Herbicidal combinations of the present invention is to adopt physical method processing, no coupling product in the production process, and three-waste free discharge has no adverse effects to ecotope.
7, energy consumption is low in the Herbicidal combinations production process of the present invention, and energy-saving effect is remarkable.
8, Herbicidal combinations application method of the present invention is flexible, and the operating period is wide, is convenient to promote.
Following the present invention is described in detail in conjunction with specific embodiments, and visible advantage of the present invention is more obvious.
