Abstract
The invention relates to four kinds of herbicidal compositions for cornfields including fluroxypyr and acetochlor composition, fluroxypyr and prometryne composition, fluroxypyr and fenoxaprop-p-ethyl composition, and fluroxypyr and isoproturon composition, the compositions have the advantages of high activity, small amount of administration, low cost, wide weeding spectrum and higher safety.
Description
Technical field the present invention relates to four kinds of Herbicidal combinations of wheat weeds, i.e. fluroxypyr and acetochlor composition, fluroxypyr and prometryn composition, fluroxypyr and smart Evil azoles diclofop-methyl composition, fluroxypyr and isoproturon composition.
Background technology is along with the development of chemical weed control technology, China's chemical weed control area rapid growth, and the initial stage nineties is 2,300 ten thousand hm2, now nearly 6,100 ten thousand hm2.But along with long-term, the large scale application of weed killer herbicide, many outstanding problems appear in the farmland weed chemical harnessing, and weeds resistance, population succession and drug injury problem are more and more serious.At present, there is such-and-such drawback in medicament commonly used in the wheatland.Green sulphur is grand, metsulfuron-methyl etc., because the longevity of residure is long, very easily succession crop is caused poisoning; 2,4-D, methoxone medication period is improper or consumption is higher, very easily to causing poisoning when a stubble wheat, and easily broad leaf crop is on every side caused the drift poisoning, and pollute sprayer; The tribenuron-methyl consumption is too high, party causes poisoning to back stubble peanut, soybean etc. excessively.In addition, because certain weed killer herbicide of single use all the year round cause susceptible weeds quantity to descend, and insensitive weeds quantity rises, and causes that weed community changes.Many drug resistance weeds also rise to the field main weeds gradually, become emerging malignant weed.Before 2000, Shandong Province wheat paddock weeds are dominant population with descurainia sophia (l.) webb ex prantl, shepherd's purse, many emerging malignant weeds appear now, as clearvers, wartwort, corn gromwell, Arabic Veronica, wild oat, amur foxtail, Wang grass, candle grass, rescuebrome, hard grass, hold, humulus grass etc., medicament commonly used is difficult to prevent and kill off, and seriously reduces crop yield and influence results.At present, research broad weed-killing spectrum, safety, efficient, low consumption, low cost, wield weed killer herbicide new varieties are an urgent demands of current agricultural production.
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 broad weed-killing spectrum, good, the tangible characteristics of synergistic effect of safety again, to overcome the problem that occurs in the present production, provide available disposable herbicide conscientiously for the northern China wheatland simultaneously.
Summary of the invention the present invention is by compound (I) fluroxypyr and compound (II) Acetochlor, or compound (I) fluroxypyr and compound (III) prometryn, or compound (I) fluroxypyr and the smart Evil azoles of compound (IV) diclofop-methyl, or compound (I) fluroxypyr and compound (V) isoproturon are formed to be mixed and are realized.Chinese and English common name and the structural formula of compound (I), (II), (III), (IV), (V) are as follows:
