The invention also provides application of the above herbicidal composition in the prevention and control of weeds in crops. Through the above technical solution, the herbicidal composition of the present invention can achieve significant synergic control effect, thus improving the performance of the herbicide.
Description
Technical field
The present invention relates to agriculture field, particularly, relate to the purposes of a kind of herbicidal composition and this herbicidal composition.
Background technology
Farmland weed generally refers to the plant of non-cultivation in the field of crops.Farmland weed survived in the ecotopes such as local crop, cultivation, farming, soil, weather and social condition in long-term adaptation, encroached on crop from many aspects.It and crops fight for water, fertilizer, luminous energy etc., occupy on the ground and the underground space, affect crop photosynthesis, and interference plant growth, affect seed output and quality, many weeds are again the germ of damage to crops, the vector of insect.Weeds are formidable enemies of agricultural production, and weeds do not remove, and finally cause crop failure.The weeds of main harm crops have: lady's-grass, barnyard grass, green foxtail, eleusine indica, wild oat, Amaranthus retroflexus, acalypha copperleaf, kitchen garden, dayflower, Siberian cocklebur, black nightshade, piemarker etc.
At present, major herbicides kind for preventing and kill off farmland weed has: acetamide-group herbicides, as butachlor, Acetochlor etc., and such weed killer herbicide and isopropyl methoxalamine ratio, poor to corn safety, north temperature in early stage is low, and suppress corn growth, early stage is not long, later stage high temperature excessive growth, remaining green when it is due to become yellow and ripe late-maturing, corn kernel moisture is large, the underproduction and deficiency in economic performance; Triazine herbicide: as atrazine, cyanazine etc., this type of weed killer herbicide is larger by the impact in environmental condition, plant growth period on the safety of crop, especially rain after dispenser and easily poisoning occurs, the longevity of residure is long, and long-term a large amount of use easily causes groundwater contamination, the deterioration of the ecological environment and have impact to the safety of succession crop; Sulfonylurea herbicide: as grand in nicosulfuron, rimsulfuron, thiophene phenol sulphur etc., such weed killer herbicide is generally used for cauline leaf process, the susceptibility of different corn varieties to this kind of medicament is variant, the probability and the severity that produce poisoning are higher, corn is easily caused to tiller increase, meet high temperature during spray medicine and can produce poisoning, and herbicide spectrum is narrower; Acid imide weed killer herbicide: as flumioxazin, flumicloracpentryl, cinidon-ethyl etc., is mainly used in preventing and treating broad leaved weed, efficient to Siberian cocklebur, black nightshade, piemarker, lamb's-quarters, morning glory, kitchen garden etc. especially.
Along with the increase of weed killer herbicide using dosage and number of times, the pesticide resistance of weeds to existing weed killer herbicide increases gradually, causes weed killer herbicide to there is the lower defect of preventive effect.
Summary of the invention
The object of the invention is to overcome the lower defect of weed killer herbicide usefulness, the herbicidal composition that a kind of usefulness is higher is provided.
To achieve these goals, the invention provides a kind of herbicidal composition, this herbicidal composition contains 2,4-drips different monooctyl ester, piperazine humulone and isopropyl methoxalamine, relative to 2 of 1 weight portion, 4-drips different monooctyl ester, and the content of piperazine humulone is 0.01-90 weight portion, and the content of isopropyl methoxalamine is 0.05-50.
