Abstract
The invention discloses a glufosinate-fluazifop p butyl compounded herbicide composition which comprises effective components, namely glufosinate and fluazifop p butyl, and the weight ratio of the glufosinate to the fluazifop p butyl is 15:(1-3). The compounded herbicide composition is prepared into water soluble granules, and comprises the effective components and additives, wherein the additives comprise a dispersing agent, a wetting agent, a disintegrating agent, and a binder or stuffing. The preparation method comprises the following steps: adding a moderate amount of water into the raw materials in a double-screw conical blender or a trough-type blender and then uniformly mixing, thus obtaining a powdered composition; then, carrying out granulation on the powdered composition by using a granulator and removing water in the obtained composition by using a drying device, thus obtaining a granular composition. The compounded herbicide composition has the advantages of low toxicity, expanded herbicide controlling spectrum, complementary advantages, good quickly available and effect-persistent properties and low cost, therefore, the compounded herbicide composition is an ideal variety for controlling weeds in citrus parks and on non-cultivated lands; meanwhile, the compounded herbicide composition is simple and safe in use and good in environmental compatibility; and compared with other herbicide compositions, the herbicide composition disclosed by the invention can be used for slowing the generation of drug resistance, carry outing weeding cleanly, thoroughly and quickly without environmental pollution and the like.
Description
Technical field
The present invention relates to a kind of control uncultivated area weeds composition pesticide, compound pesticide composition of particularly careless ammonium phosphine and efficient fluazifop and preparation method thereof.
Background technology
In recent years; Because a large amount of uses of various agricultural chemicals; Cause the agricultural weed pesticide resistance increasingly high; As eleusine indica, annual bluegrass, flat fringe nutgrass flatsedge, Bermuda grass, barnyard grass grass, perennial ryegrass, creeping bentgrass, cyperus iria, difformed galingale herb, lady's-grass, broomwort, false stinkweed, carpet weed, the rich flowers and plants of rough leaf, hairy euphorbia, emarginate amaranth herb or seed, amur foxtail, alternanthera philoxeroides (revolution grass), chickweed, Horseweed Herb, Veronica, kitchen garden, four give birth to arm shape grass, corydalis, field bindweed, knotweed, shepherd's purse, common sow thistle, Asiatic plantain, Herba Ranunculi Japonici, babysbreath, Groundsel etc. or the like; Harm is serious throughout the country, and is total in the control of chemical agent, and single agent such as main at present use glyphosate, paraquat, careless ammonium phosphine all produce very strong pesticide resistance; The mu using dosage increases year by year; Use cost increases year by year, and quick-acting is poor, and certain limitation is in use arranged.
Grass ammonium phosphine is a kind of organic phosphates weed killer herbicide, glutamine synthetase inhibitor, non-selective contact weedicide.Certain systemic action is arranged; Can be used for orchard, vineyard, uncultivated area weeding; Prevent and kill off annual or perennial dicotyledonous and grassy weed and nutgrass flatsedge etc., like mouse tail amur foxtail, lady's-grass, barnyard grass, green foxtail, wild wheat, wild corn, orchardgrass, fescue grass, bent awns hairgrass, yorkshire fog grass, perennial ryegrass, reed, annual bluegrass, wild oat, bromegrass, clearvers, benbie, deaf nettle, black nightshade, chickweed, quackgrass, bent grass, stroke son grass, field scorpion grass, Bermuda grass, Amaranthus retroflexus etc. with also can be used for potato.
Efficient fluazifop is the lethality during the cauline leaf inorganic agent has to life in 1 year and perennial grassy weed behind a kind of inner sucting conduction type, the high selectivity seedling, and is to broad leaf crop safety, invalid to broadleaf weed.Weeds mainly absorb through cauline leaf receives conduction, and root also can absorb conduction.Poisoning symptom can occur in 48 hours after the general dispenser, then need 15 days but thoroughly kill weeds.The scope of application is applicable to various crop such as soybean, cotton, beet, potato, sweet potato, peanut, pea, broad bean, Kidney bean, tobacco, flax, watermelon, reaches rubber, fruit tree, plantation, forestry nursery, tending [after young plantation etc.Prevent and kill off life in 1 year and perennial grassy weed, like non-irrigated barnyard grass, green foxtail, lady's-grass, eleusine indica, wild swallow grass, amur foxtail, bromegrass, arm shape grass, reed, Bermuda grass, Paspalum distichum etc.
