Abstract
A water suspending agent for weeding in a soybean field comprises the following components in percentage by weight: 5-15% of fluazifop-P, 5-10% of fluthiacet methyl, 8% of a surface active agent pluronic125, 5% of propylene glycol, 8% of xanthan gum, 1% of methyl esterification plant water, and the balance of water. The suspending agent provided by the invention is obvious in weeding effect; compared with fomesafen, the solvent of the suspending agent is water, so that the suspending agent is relatively environment-friendly, has low possibility of inflaming in the transportation process, is relatively safe and low in cost, improves the control effect, the fresh weight control effect and the comprehensive fresh weight control effect on weeds in the field, is safe for crops in the field, can prevent and kill weeds in the whole growing period of the crops after being used once, is safe for next-stubble crops, and is a relatively ideal weedicide for treating later steams and leaves of soybean seedlings currently.
Description
Technical field
The present invention relates to pesticide field, particularly a kind of Soybean Field weeding aqueous suspension agent.
Background technology
Soybean is one of important cereal crops of China, existing 5,000 years cultivation histories.The Soybean Field main weeds has: lady's-grass, green foxtail, barnyard grass, amaranth, piemarker, kitchen garden, acalypha copperleaf, Siberian cocklebur, grey dish, orchid dish, field dobber, sorrel are few etc.The weed killer herbicide of the management of weeds that current Soybean Field is main is Quizalotop-ethyl, fomesafen etc., and due to long-term use, resistance improves, and causes dosage large, and environmental pollution, also increased peasant's dispenser cost.And efficient fluazifop and fluthiacet composite prevent and kill off soybean weeds report seldom arranged.
Efficient fluazifop, chemical name is: (R) 2-[4-(5-trifluoromethyl-2-pyridine oxygen base) phenoxy group] butyl propionate, molecular formula: C
15h
12f
3nO
4, molecular weight is 327.2553, is selective post-emergence herbicide.Be mainly used in the annual gramineous weed that prevent and kill off in the broad leaf crop fields such as soybean.To soybean safety.Being cauline leaf inorganic agent after seedling, is the important kind of soybean field herbicide.Be mainly used in preventing and kill off the annual and perennial grassy weeds such as barnyard grass, wild oat, green foxtail, Setaria glauca, eleusine indica, amur foxtail, moleplant seed, india lovegrass, bromegrass, Hordeum, Secale, millet genus, annual bluegrass, Bermuda grass, Paspalum distichum, false Chinese sorghum, reed, wild silkworm, cogongrass, quackgrass.
Fluthiacet, chemical name:: [[the fluoro-5-[(tetrahydrochysene of the chloro-4-of the 2--inferior pyridazine of 3-oxo-1H-3H-(1,3,4) thiadiazoles [3,4a]-1-yl) amino] phenyl] sulphur] methyl acetate; Molecular formula is Cl5H15ClFN3O3S2, and molecular weight is 403.88, for cauline leaf after tagging property seedling, processes weed killer herbicide, mainly prevents and kill off the broad leaved weeds such as corn, Soybean Field piemarker, lamb's-quarters, smartweed grassy weed is not prevented and kill off to effect.
