Abstract
The invention relates to a novel pesticide composition containing ethoxysulfuron. The composition is a ternary compound herbicide composition consisting of the following active ingredients in part by weight: 1 to 40 parts of ethoxysulfuron, 5 to 60 parts of mefenacet and 10 to 80 parts of benthiocarb; and the composition can be prepared into wettable powder, water dispersible granules, suspending agent, emulsion, micro emulsion or emulsion in water. The pesticide composition is used for preventing and controlling annual weed of paddy fields.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of new pesticide combination containing ethoxysulfuron, for the weeds that water prevention rice field is common.
Background technology
The direction of pesticide developing embodies efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three is high ", namely (1) safety is high, and this not only requires that toxicity is low, residual low, and nuisanceless; (2) biologically active is high; (3) selectivity is high.Therefore continue to improve the performance of current Pesticidal products, reach efficient, low toxicity, free of contamination requirement.So selected the agricultural chemicals of composite mixture just to become current first-selection and the effective approach of one is that the agricultural chemicals of performance complement obtains best synergistic effect by adjusting the proportioning of different agricultural chemicals.

Benthiocarb (thiobencarb), molecular formula: C

16clNOS, chemical name: S-[(4-chlorphenyl) methyl] diethyl thiocarbamate, this medicine is carbamates selectivity inner sucting conduction type soil processing herbicide, can be absorbed by the root of weeds and young shoot, particularly young shoot is transferred in plant corpus after absorbing, and has very strong inhibitory action to growing point.Benthiocarb hinders α-amylase and protein synthesis, also has strong inhibition effect to the mitosis of plant cell, thus causes the weeds at the weed seed of sprouting and the initial stage of sprouting withered.The speed of barnyard grass Assimilation and conductivity benthiocarb is faster than paddy rice, and the speed of degradation in vivo benthiocarb is slower than paddy rice, and this forms optionally physiological foundation.This type of weed killer herbicide can rapidly by adsorption by soil, and the leaching thus with moisture is little, is generally distributed in soil layer 2 centimeters.The suction-operated of soil decreases the loss caused by evaporation and photodissociation.Half life period in soil, being 2-3 week under ventilation good condition, is then the 6-8 month under anaerobic condition.By soil microbial degradation, by the dechlorination benthiocarb that edaphon is formed under anaerobic condition, can suppress paddy growth consumingly.
The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Therefore, their herbicide ability and scope also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds being difficult to elimination with other weed killer herbicide.
In recent years, people frequently use the so-called selective herbicide having the safety to useful crop and the herbicidal effect to undesirable plant concurrently, but even there is the weed killer herbicide of high selectivity, in use because of the various condition such as kind, chemicals treatment period of meteorological condition, soil condition, crop, sometimes also produce poisoning.People are studying the use of the various poisoning palliatives of the so less desirable state of affairs of reply.At present, China also comparatively payes attention in the mixed research of weed killer herbicide, is widely regarded as one of important measures of weed killer herbicide reasonable employment, investigated a series of Herbicidal compositions, achieves greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, the relevant compound product about ethoxysulfuron, mefenacet and benthiocarb has no report.

Dispenser place: large lotus flower village, suburb, Tieling, Liaoning Province
Investigation method and drug effect calculate
Investigation weeds object is: the weeds such as difformed galingale herb, barnyard grass, needle spikesedge herb, after investigation medicine 10 days, 30 days to the strain preventive effect of weeds and the fresh weight preventive effect of 30 days.
Visual test medicament occurs without poisoning paddy rice.
Test results and analysis are respectively in table 2.
The table 2 ethoxysulfuron mefenacet benthiocarb water prevention weeds in paddy field test of pesticide effectiveness one
Table 2 ethoxysulfuron mefenacet benthiocarb and the built composition for preventing and controlling paddy field weed test of pesticide effectiveness one thereof
Ethoxysulfuron mefenacet benthiocarb is composite as shown in Table 2 has good control efficiency to weeds such as paddy field difformed galingale herb, barnyard grass, needle spikesedge herbs, preventive effect is better than single dose preventive effect, and find through test people, ethoxysulfuron, mefenacet and benthiocarb are composite all has good preventive effect to paddy field dichotomous fimbristylis herb, firefly Lin, Eclipta prostrata, pondweed, beggar-ticks, grass dragon, false loosestrife, mexicana, water three-coloured amaranth, amur foxtail, lady's-grass, and after medicine, 30 days preventive effects reach more than 90%.With contrast medicament, artificial weeding, relative to clear water control treatment rate of growth between significant difference, and there is good quick-acting and lasting effect, in this experimental drug scope, to rice safety.
Application Example four: ethoxysulfuron mefenacet benthiocarb water prevention weeds in paddy field field efficacy
Test two
Dispenser place: Guangxi province Nanning City Wuming County
Investigation weeds object is: the weeds such as cyperus iria, pondweed, bur beggar-ticks, and within after investigation medicine 10 days, 30 days, to the strain preventive effect of weeds and the fresh weight preventive effect of 30 days, computational methods are same as above.
Visual test medicament occurs without poisoning paddy rice.
Test results and analysis are respectively in table 3.
