Good wheatland disposable herbicide
The invention belongs to the cornfield herbicidal 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.Cornfield herbicidal several years ago mainly contains nitrofen, Acetochlor, chlortoluron, 2, kind such as 4-D, methoxone, these kinds are because herbicidal effect is low, consumption is big, cost is high, grand by the green sulphur of sulfonylurea herbicide in recent years, metsulfuron-methyl replaces, see " external new varieties of pesticides handbook (Sha Jiajun, Zhang Minheng, Jiang Yajun, Chemical Industry Press), 1992.10, P449,446.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 soil residual life, influence to succession crop is fairly obvious, particularly to the north of China the Changjiang river wheat-cotton crop rotation district, wheat-soybean crop rotation district, wheat-corn crop rotation district, wheat-zones such as beet crop rotation district have been prohibited is applied to cornfield herbicidal.Metsulfuron-methyl is more outstanding in the problem on residual, not only the broad leaf crop to the back stubble seriously influences, and also very big to the influence of back stubble paddy rice, have a strong impact on the output of paddy rice, active in addition high, careless slightly, to working as a stubble crop also poisoning can take place, poor stability, therefore, the complex weedicide that is used for cornfield herbicidal in recent years again in test, 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.
The present invention is by compound (I) tribenuron-methyl and compound (II) carfentrazoneethyl, or compound (I) tribenuron-methyl and compound (III) fluroxypyr, or compound (I) tribenuron-methyl and compound (IV) fluoroglycofen-ethyl and compound (I) tribenuron-methyl and compound (combination of V) oxazole diclofop-methyl is mixed and realizes.
The structural formula of compound (I), (II), (III), (IV), (V) is as follows:

Advantage of the present invention is that significantly it mainly shows:
1, Herbicidal combinations of the present invention, no any antagonism between each composition, synergistic effect is remarkable.
2, being key component according to the present invention with two kinds of compounds is mixed when using by the present invention, and the agent of amount ratio list is used and significantly reduced, and has reduced cost, can reduce farmer's burdens.
3, Herbicidal combinations of the present invention with use separately single effective ingredient relatively, enlarged and killed the grass spectrum, a weeding, it is better to save the season herbicidal effect from damage.
4, Herbicidal combinations of the present invention, overcome the defective of super-high-efficient weed killer herbicide, provide the highy potent herbicide new varieties in particular for northern China wheat-cotton crop rotation district, wheat-beans crop rotation district, wheat-corn crop rotation district, wheat-beet crop rotation district to the succession crop poor stability.
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.
