Abstract
The invention relates to a medium-term chemical herbicide for crops. The medium-term chemical herbicide is prepared from the following materials in percentage by weight: 20%-45% of metolachlor, 1%-24% of oxyfluorfen, 3%-18% of emulsifier, 0%-10% of penetrating agent and the balance being solvent. The herbicide can be applied to a parcel of rice field in which weeds just come out after intertillage so as to achieve the effects of weeding and heaping earth. The herbicide can be widely applied to weeding at medium terms of the crops such as paddy, cotton, corn, soybeans, peanuts and vegetables, can generate a high synergistic effect, and can be used for effectively preventing and eliminating a plurality of seasonal gramineous weeds and broadleaf weeds.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of crop chemical herbicide in mid-term.
Background technology
Traditional two kinds of modes of having cut weeds: a kind of is to rely on artificial or apparatus weeding, and this kind of weeding system labour intensity is large, and efficiency is low, and is easy to injure rhizome, affects plant growth, after crop emerges, with regard to more inconvenient, carries out manually or the apparatus weeding again.Another kind of weeding system is chemical weed control, generally selects single dose to carry out weeding, has many drawbacks, the one, and dangerous to crop, dominant or recessive poisoning appears, suppress the growth of crop, cause crop failure; The 2nd, herbicidal effect is poor, and the herbicide spectrum is narrow, and effective drug duration is short, and herbicide is not thorough, loses control of crop smothering.
Summary of the invention
The present invention is in order to make up the prior art deficiency, provides that a kind of safe and efficient, broad weed-killing spectrum, effective drug duration are long, easily simple operations, economical and practical a kind of crop chemical herbicide in mid-term, can effectively prevent and kill off grassy weed, also can effectively prevent and kill off broad leaved weed.
A kind of crop chemical herbicide in mid-term of the present invention, be formulated by following weight ratio by isopropyl methoxalamine, Oxyfluorfen, emulsifier, bleeding agent and solvent: isopropyl methoxalamine 20% ~ 45%, Oxyfluorfen 1% ~ 24%, emulsifier 3% ~ 18%, bleeding agent 0% ~ 10%, surplus are solvent.
Isopropyl methoxalamine mainly absorbs by young shoot, upwards conduction, suppress the growth of young shoot and root, the protein of the main sprout inhibition seed of mechanism of action is synthetic, next suppresses choline and infiltrates phosphatide, interference lecithin forms, and the energy force rate broad leaved weed that absorbs isopropyl methoxalamine due to the grassy weed young shoot is strong, thereby the effect that this medicine is prevented and kill off grassy weed is better than broad leaved weed far away.
Oxyfluorfen is the contact killing type weed killer herbicide, in the situation that its activity of weeding of light performance is arranged, mainly by coleoptile, mesocotyl, enter in plant corpus, less through root absorption, and there is denier to make progress and transport the leaf section that enters by root, for before cotton, round onions, peanut, soybean, beet, fruit tree and vegetable fields bud, use after bud and prevent and kill off barnyard grass, sesbania, downy brome, green foxtail, datura, quackgrass, artemisiifolia, thorn chrysanthemum sth. made by twisting, piemarker, charlock unifacial leaf and broad leaved weed, its very anti-leaching, can be made into missible oil and use.Can prevent and kill off unifacial leaf and the broad leaved weed of transplanting rice, soybean, corn, cotton, peanut, sugarcane, vineyard, orchard, vegetable fields and forest nursery.The dryland rice dispenser can be mixed with butachlor; In dispensers such as soybean, peanut, Cotton Fields, can be mixed with alachlor, trefanocide etc.; Locate dispenser in orchard etc., can be mixed with paraquat, glyphosate.
Good effect of the present invention is: a kind of crop chemical herbicide in mid-term of the present invention, and the field that after can being applied to intertill after preparation, weeds have just emerged, reach the effect of weeding grave mound; Can be widely used in crop weedings during mid-term such as paddy rice, cotton, corn, soybean, peanut, vegetables, can produce higher synergistic effect, can effectively prevent and kill off multiple seasonal grassy weed and broad leaved weed.
