Abstract
The invention discloses a weeding composition for paddy fields. The weeding composition is prepared by the combination of active ingredients of pyrazosulfuron-ethyl and mesotrione, wherein the weight ratio of pyrazosulfuron-ethyl to mesotrione is 1: (1-12). The weeding composition can be formulated into wettable powder, water dispersible granules, suspensions and the like. The weeding composition has the characteristics of being high-efficiency in weeding effect, wide in weeding spectrum, low in residue, safe for crops, low in cost and relatively good in control effect on broad-leaved weeds and grassy weeds, and the weed hazards of the paddy fields in the entire season can be basically controlled by one-time use of the weeding composition.
Description
Technical field:
The present invention relates to a kind of Herbicidal composition for rice field, belong to technical field of pesticide.The present invention further relates to pyrazosulfuron and the composite Herbicidal composition for rice field of mesotrione, its various dosage forms, the preparation method and its usage of above-mentioned Herbicidal combinations.
Background technology:
Paddy rice is the crops of China's cultivated area maximum, paddy field common weed kind approximately has 100 kinds, continuous expansion along with its cultivated area, the harm of rice field crop smothering is also day by day serious, and can effectively control crop smothering in paddy rice, make paddy rice stablize high yield, also become one of major subjects of modern agricultural herbicide research.Chemical weed control is the most reliable and the most cheap method of weed control of current paddy field.It is narrow that there is herbicide spectrum in the weed killer herbicide of paddy field at present, can not effectively to Tanaka's broad leaved weed and grassy weed, play extraordinary control efficiency simultaneously, so find, use safety, have broad herbicidal spectrum, efficient cheap herbicide for paddy field is the problem that agrotechnical worker studies always.。
Pyrazosulfuron is a kind of sulfonylurea herbicide, and side chain amino acid synthetic inhibitor, for transplanting or direct seading rice field, is prevented and kill off broad leaved weed and nutgrass flatsedge, and grass family is only had to inhibitory action.
Mesotrione is a kind of novel three ketones weed killer herbicide, both can seedling before native list processing, also can seedling after cauline leaf spraying.It has interior absorption, can be absorbed rapidly by plant roots and blade, and conduct rapidly at phloem and xylem, can effectively prevent and treat broad leaved weed and some grassy weeds, but its metabolism and inactivation rapidly in paddy rice body, so to paddy rice high safety.Its degraded rapidly in soil of while, consumption is low, and noresidue when Crop is also friendly to environment, is current comparatively desirable weed killer herbicide.
Inventor finds after deliberation, pyrazosulfuron and mesotrione carry out the composite very significantly synergistic effect that has, control efficiency to crop weeds increases significantly, and can expand herbicide spectrum, double grass family and the broad leaved weed controlled, reach the double object of controlling single, double cotyledon weeds of applied once, reduce weeding dispenser recruitment cost, finally reach the object that improves rice yield.

Drug effect embodiment
Drug effect embodiment 1: pyrazosulfuron synergistic effect to weeds research mixed with mesotrione
This test objective is under greenhouse experiment, and by pot experiment, pyrazosulfuron is mixed with mesotrione that weeds are made to type mutually in research.For trying target: barnyard grass (Echinochloa crus-galli) and carp intestines (Eclipta prostrata).Weeds condition of culture: the cultivation for examination weeds is carried out in the light incubator of weeds chamber.With 300 grams of loams of 9cm X9cm plastics, broadcast 50, barnyard grass or carp intestines seed, seed level 0.2-0.3cm for every glass.Before sowing, soak seed 24 hours.After planting be placed on greenhouse growth.Soil for examination is loam.Duration of test, once keeps soil at moisture state every one day water spray.
Reagent agent: the former medicine of pyrazosulfuron and mesotrione.
Test is processed: according to trial test result, pyrazosulfuron establishes 10 and 15g a.i./hectare, mesotrione establishes 30,60,90g a.i./hectare, and pyrazosulfuron+mesotrione is established 10+30 (1: 3), 10+60 (1: 6), 10+90 (1: 9), 15+30 (1: 2), 15+60 (1: 4) and six ratios of 15+90 (1: 6) g a.i./hectare.Separately establish a nonuser contrast.After planting second day spray medicine.With quantitative spray tower spray medicine, during spray medicine, spouting liquid is 10ml/0.198m
2.Every processing repeats 4 numbers.
Data survey and statistical analysis: after dispenser 35 days, overground part is cut, weigh immediately, be calculated as follows inhibiting rate.
Inhibiting rate (%)=(contrast fresh weight-processing fresh weight)/contrast fresh weight * 100
Theoretical inhibiting rate (E) is calculated as follows:
E (%)=mesotrione inhibiting rate+(100-mesotrione inhibiting rate) * pyrazosulfuron inhibiting rate/100
The judgement of the interaction effect of compound drug:
The theoretical inhibiting rate of actual inhibiting rate >, shows synergistic effect;
Actual inhibiting rate=theoretical inhibiting rate, shows addition;
The theoretical inhibiting rate of actual inhibiting rate <, shows antagonism.
Interpretation of result and discussion
The alone 10 and 15 grams of a.i./hectares of pyrazosulfuron are respectively 21.9% and 42.4% to barnyard grass growth inhibition ratio, and the inhibiting rate of carp intestines is respectively to 56.6% and 65.1%.Alone 30, the 60 and 90 grams of a.i./hectares of mesotrione are respectively 40.0%, 53.5 and 67.1% to barnyard grass growth inhibition ratio, and the inhibiting rate of carp intestines is respectively to 45.6%, 64.9% and 66.2%.
Pyrazosulfuron+mesotrione 10+30 (1: 3), 10+60 (1: 6), 10+90 (1: 9), 15+30 (1: 2), 15+60 (1: 4) and 15+90 (1: 6) g a.i./hectare ratio is mixed that barnyard grass growth inhibition ratio is respectively to 66.1%, 74.5%, 84.8%, 77.1%, 83.2% and 92.0% are all high more than 10% (table 1) than the theoretical inhibiting rate calculating by Colby method.This result shows that mesotrione activity to barnyard grass mixed with pyrazosulfuron has synergistic effect.Pyrazosulfuron+mesotrione, under above-mentioned mixed ratio, is respectively 89.5%, 96.9%, 97.3%, 96.1%, 99.7% and 98.7% to carp intestines growth inhibition ratio, also all high more than 10% than theoretical inhibiting rate.This result shows that pyrazosulfuron is mixed with mesotrione also has synergistic effect (table 2) to carp intestines activity.
Mesotrione is mixed with pyrazosulfuron to be shown as result of the test mutually, and pyrazosulfuron+mesotrione, in 1: 2～9 mixed scopes, has synergistic effect to weeds activity.
Table 1. pyrazosulfuron+mesotrione is mixed to the active formulation screening test result of barnyard grass
Table 2. pyrazosulfuron+mesotrione is mixed to the active formulation screening test result of carp intestines
Drug effect embodiment 2.25% pyrazosulfuron+mesotrione (5%+20%) wetting powder field effect
For the chronergy of clear and definite 25% mesotrione+pyrazosulfuron wetting powder field management of weeds, evaluating drug effect is carried out in field northeastward.The dosage that test is processed is 20 and 30 grams every mu, establishes a no contrast, repeats four times.In transplanting, within latter 12 days, mixing pesticide-clay mixture spreads fertilizer over the fields.30 days investigation weeds fresh weights after dispenser.
After dispenser, 30 days investigation results show, 20 and 30 grams every mu of 5% mesotrione+pyrazosulfuron wetting powders fresh weight preventive effect to Monochoria vaginalis is respectively 90.1% and 98.5%, and the fresh weight preventive effect of barnyard grass is respectively to 86.8% and 91.3%.
