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 fields of crops. Farmland weed survived in the ecological environments such as local crop, cultivation, farming, soil, weather and social condition in long-term adaptation, encroached on from many aspects crop. It and crops fight for water, fertilizer, luminous energy etc., occupy on the ground and the underground space, affect crop photosynthesis, disturb plant growth, affect output and quality, and 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 bristlegrass, eleusine indica, wild oat, Amaranthus retroflexus, acalypha copperleaf, purslane, dayflower, Siberian cocklebur, black nightshade, piemarker etc.
At present, have for the main herbicide kind of preventing and kill off farmland weed: acetamide-group herbicides, as butachlor, Acetochlor etc., such herbicide and isopropyl methoxalamine ratio, to corn poor stability, north temperature in early stage is low, suppresses corn growth, and 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 herbicide is subject to the impact in environmental condition, plant growth period larger on the security of crop, especially after dispenser, rain poisoning easily occurs, the longevity of residure is long, and long-term a large amount of uses easily cause underground water pollution, the deterioration of the ecological environment and the security on succession crop to have impact; Sulfonylurea herbicide: as grand in nicosulfuron, rimsulfuron, thiophene phenol sulphur etc., such herbicide is generally used for cauline leaf processing, different corn varieties are variant to the sensitiveness of this class medicament, the probability and the severity that produce poisoning are higher, easily cause the corn increase of tillering, when spray medicine, meet high temperature and can produce poisoning, and herbicide spectrum is narrower; Acid imide herbicide: as flumioxazin, flumicloracpentryl, cinidon-ethyl etc., be mainly used in preventing and treating broad leaved weed, efficient to Siberian cocklebur, black nightshade, piemarker, lamb's-quarters, morning glory, purslane etc. especially.
Along with the increase of herbicide using dosage and number of times, weeds increase gradually to the resistance to the action of a drug of existing herbicide, cause herbicide to have the defect that preventive effect is lower.
