Abstract
The present invention relates to five kinds of herbicide compositions for wheat field, including herbicide composition of bensulfuron-methyl and metsulfuron methyl, herbicide composition of bensulfuron-methyl and tribenuron-methyl, herbicide composition of bensulfuron-methyl and fluoroglycofen-ethyl, herbicide composition of bensulfuron-methyl and cafenstrole, and herbicide composition of bensulfuron-methyl and diclofop methyl. These herbicide compositions are superior to available similar herbicides and may be used in preventing and killing various weeds in wheat field, and are safe and low in cost.
Description
The invention belongs to the farmland 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 soil 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, 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, 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.
Bensulfuron is good herbicide for paddy field, all fool proof to working as stubble crop and succession crop under the early stage of quality guarantee, apply during the last ten years in China, become the govern-house-variety of China's agent for removing grass in paddy field, at present, all contain bensulfuron in China's built herbicide for rice field in the major part, for significant contribution has been made in the agricultural agricultural high yield good harvest of China.
The present invention is by compound (I) bensulfuron and compound (II) metsulfuron-methyl, or compound (I) bensulfuron and compound (III) tribenuron-methyl, or compound (I) bensulfuron and compound (IV) fluoroglycofen-ethyl, or compound (I) bensulfuron and compound (V) carfentrazoneethyl, or compound (I) bensulfuron and compound (VI) oxazole diclofop-methyl combination is mixed and realizes.
The structural formula of compound (I), (II), (III), (IV), (V), (VI) is as follows:
Compound (I): bensulfuron
Compound (II): metsulfuron-methyl
Compound (III): tribenuron-methyl
Compound (IV): fluoroglycofen-ethyl
Compound (V): carfentrazoneethyl
Compound (VI): oxazole diclofop-methyl
Wherein the part by weight of compound (I) bensulfuron and compound (II) metsulfuron-methyl is 10: 0.05-5,
The part by weight of compound (I) bensulfuron and compound (III) tribenuron-methyl is 10: 0.1-50,
The part by weight of compound (I) bensulfuron and compound (IV) fluoroglycofen-ethyl is 10: 1-100,
The part by weight of compound (I) bensulfuron and compound (V) carfentrazoneethyl is 10: 1-100,
(part by weight of VI) oxazole diclofop-methyl is 10: 10-1000 for compound (I) bensulfuron and compound
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.
Following the present invention is described in detail in conjunction with specific embodiments, so that advantage of the present invention is more obvious.
