In recent years, China's weed killer herbicide is used area and is constantly enlarged, the output of weed killer herbicide and consumption are also improving year by year, though the weed killer herbicide of single variety is fine to the weed control efficacy in some crop field, but since single weed killer herbicide to kill the grass spectrum narrower, in most of occasion, it is not comprehensive to kill careless ability, preventive effect is undesirable, also some crop is existed potential poisoning danger simultaneously.Therefore, use exploitation with complex preparation with between the weed killer herbicide, become one of main developing direction of weed killer herbicide industry, use with and the composite decapacitation of weed killer herbicide enlarge the careless scope of killing, and improve outside herbicidal effect and the selectivity, can also reduce the dosage of weed killer herbicide, reduce agricultural cost relatively, and the longevity of residure of shortening medicament, avoid poisoning to make crop safety, thereby the composite main developing direction that has become the developmental research of weed killer herbicide industry of weed killer herbicide.
Acetochlor belongs to known acetamide-group herbicides, because its good preventive effect and to the adaptability of various crop, welcome by the peasant, but Acetochlor also has certain shortcoming: 1. safety is lower, and consumption is too high can to cause poisoning; 2. it is narrow partially to kill the grass spectrum, and with respect to some other weed killer herbicides, the careless spectrum of killing of Acetochlor should be a broad, but at different times, the Different Crop field, still poor, especially relatively poor to the preventive effect of some broad leaved weeds to some weed control efficacy.Prometryn is a kind of triazine herbicide, and grass spectrum is wider extremely for it, weeds are suppressed effective, but its major defect is relatively poor to the preventive effect of grassy weed, and dangerous to crop.Since Acetochlor and prometryn kill aspect the careless spectrum can complementation and expansion kill careless scope, can reduce the dosage of single variety after both are composite, raising is to the safety of crop, and synergistic effect is arranged, therefore domestic and international pesticide industry has been carried out the developmental research to compounded technology and application technology between Acetochlor and the prometryn.
On February 18th, 1998, disclosed application number was that disclosing a kind of in 97115089.3 patent application specifications is the mixture preparation of Main Ingredients and Appearance with Acetochlor and prometryn, wherein the weight ratio between Acetochlor and the prometryn is 1: 0.01-1: 50, formulation is pulvis or wetting powder, and has listed the test data paddy rice, cotton, soybean field management of weeds.This patent application exists following shortcoming and defect:
(1) Acetochlor and the prometryn mixed ratio of enumerating in this patent application right requirement and the specification is 1: 0.01-1: 50, and scope is wide, almost can't implement.As everyone knows, two kinds of mutual synergistic effects of dissimilar weed killer herbicides should have a synergy ratio range, outside this scope, poor effect, also can expose simultaneously the drug injury problem of a certain composition, have only through conscientious prescription screening and virulence and evaluation of pesticide effectiveness test, just can filter out the formula range that to implement, thereby provide a kind of mixture of herbicides technology and product with " practicality ".
(2) active ingredient of enumerating in this patent application document (Acetochlor+prometryn) and the weight proportion of solid carrier are 1: 0.01-1: 10 similarly to exist scope wide, wherein there is sizable part to implement, and for can make can be practical pulvis or the ratio range of wetting powder, not open in the specification.
(3) the processing formulation of this patent is pulvis or wetting powder, the dispersion effect of preparation own is relatively poor, especially for dry crop such as fields of peanut and other crops during as the soil surface inorganic agent, owing to disperse bad, be difficult for forming complete closing membrane, thus bigger to the drug effect influence.
(3) summary of the invention
In order to solve the shortcoming and defect that exists in aforementioned Acetochlor and the Prometryn weedicide composition prior art, the inventor screens the formula range of Acetochlor and Prometryn weedicide composition, by indoor co-toxicity test, and in conjunction with drug cost and to the factors such as safety of crop, select the ratio range between Acetochlor+prometryn, selected to help improving the formulation and the processing formula of herbicidal effect at the characteristics of Acetochlor and prometryn.
Herbicidal combinations active ingredient of the present invention is Acetochlor and prometryn, its mutual part by weight scope is (10: 30)-(30: 10), optimizing the part by weight scope is (15: 25)-(25: 15), and optimum weight ratio scope is (18: 22)-(22: 18).
