Abstract
The present invention relates to four haulm herbicide compositions for weeding in cornfields, namely the herbicide compositions of fenoxaprop-P-ethyl with tribenuron, fenoxaprop-P-ethyl with carfentrazone-ethyl, fenoxaprop-P-ethyl with 2, 4-D butyl ester, and fenoxaprop-P-ethyl with MCPA-sodium. The current single herbicide for cornfield weeding with a limited weeding spectrum can not control all weeds in cornfields; the existing compounded product generates herbicide damage of various degrees to current and afterreap crops and especially can not be used in north cornfields due to long residual period and poor safety. The four herbicide compositions provided by the present invention overcome the defects, can control various weeds in cornfields and have high safety to current and afterreap crops. In addition, the haulm herbicides are applied only to weeds with strong pertinence to avoid blind herbicide application, reduce farmers' unnecessary expenses and lighten environment pollution caused by herbicide application.
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, cornfield herbicidal several years ago mainly contains nitrofen, Acetochlor, chlortoluron, 2, kinds such as 4-D, methoxone, isoproturon, these kinds or since herbicidal effect poor or since consumption big, cost is high, grand by the green sulphur of sulfonylurea herbicide in recent years, metsulfuron-methyl, tribenuron-methyl replace, see " external new varieties of pesticides handbook (Sha Jiajun, Zhang Minheng, Jiang Yajun, Chemical Industry Press), 1992.10.Green sulphur is grand, the metsulfuron-methyl weed killer herbicide has active high, few, the low cost and other advantages of consumption, but they still have relatively outstanding weak point: it is long that green sulphur swells in scholar's earth residual life, influence to succession crop is fairly obvious, particularly wheat-cotton crop rotation district, wheat-soybean crop rotation district, wheat-corn crop rotation district, wheat-beet crop rotation district easily cause poisoning to second stubble crop to the north of China the Changjiang river, even also easily a following batch paddy rice is caused poisoning in southern rice producing region; Metsulfuron-methyl belongs to the super-active weed killer herbicide, and every mu only needs medication 0.5 gram, can effectively prevent and kill off the multiple weeds of wheatland, but owing to high sensitive of plant and the phytotoxicity accident that causes than the long longevity of residure are also happened occasionally; Tribenuron-methyl is the cornfield herbicidal of comparison safety, applied rapidly in recent years, but since only effective to broad leaved weed, along with use year after year, made the grass of weeds in the wheatland that obvious variation has taken place mutually.Therefore, the complex weedicide that is used for cornfield herbicidal more in recent years arises at the historic moment, but above problem still can not be well solved.
The objective of the invention is to seek a kind of novel wheat field herbicide composition 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 wheatland weed killer herbicide commonly used, provide available cornfield herbicidal conscientiously for the northern China farmland simultaneously.
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) tribenuron-methyl, or compound (I) fenoxaprop and compound (III) carfentrazoneethyl, or compound (I) fenoxaprop and compound (IV) 2, the 4-d butyl ester, or compound (I) fenoxaprop and compound (V) 2 first 4 chlorine sodium salts combinations is mixed and realizes.
The structural formula of compound (I), (II), (III), (IV), (V) is as follows:
Compound (I): fenoxaprop
Compound (II): tribenuron-methyl
Compound (III): carfentrazoneethyl
Compound (IV): 2, the 4-d butyl ester
Compound (V): 2 first, 4 chlorine sodium salts
Wherein compound (part by weight of I) fenoxaprop and compound (II) tribenuron-methyl is 10: 0.1-50,
Compound (part by weight of I) fenoxaprop and compound (III) carfentrazoneethyl is 10: 0.5-50,
Compound (I) fenoxaprop and compound (IV) 2, the part by weight of 4-d butyl ester are 5: 1-100,
Compound (part by weight of I) fenoxaprop and compound (V) 2 first 4 chlorine sodium salts is 1: 1-100,
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 keeping 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, so that advantage of the present invention is more obvious.
