Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide containing ethoxysulfuron, for preventing and treating the common weeds of paddy field.
Background technology
The direction of pesticide developing was to embody efficient, low toxicity, low-residual and pollution-free in recent years.Be embodied in pursuit " three height ", (1) is safe, and this not only requires toxicity 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, select the agricultural chemicals of composite mixture just to become current first-selection and a kind of effectively approach, be that the agricultural chemicals of performance complement obtains best synergistic effect by adjusting the proportioning of different agricultural chemicals.

The chemical composition of each weed killer herbicide, formation and physic-chemical property are all distinguishing.Therefore, their herbicide ability and scope are also different.Some weed killer herbicide herbicide spectrum is narrower, but has one's own knack, and can eradicate the weeds that are difficult to elimination with other weed killer herbicide.
In recent years, the frequent so-called selective herbicide that has the safety to useful crop and the herbicidal effect to undesirable plant concurrently that uses of people, even but there is the weed killer herbicide of high selectivity, because of various conditions such as the kind of meteorological condition, soil condition, crop, chemicals treatment periods, sometimes also produce poisoning in use.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 to aspect the mixed research of weed killer herbicide, is widely regarded as one of important measures of rationally use of weed killer herbicide, has worked out a series of Herbicidal compositions, has obtained greater advance.
My company is also devoted to the research and development of Herbicidal compositions.At present, have no report about the relevant composite product of ethoxysulfuron, clomazone and Acetochlor.

Investigation method:
Test is processed and is estimated target be injured symptom and growth inhibition situation after 15d, and claims acrial part fresh weight, calculates fresh weight inhibiting rate (%).
Synergy evaluation method:
Evaluate weed killer herbicide mode of application (NY/T 1155.7-2006) according to Colby method, its formula is as follows:
E
0＝X×Y×Z/100
2
In formula, X be ethoxysulfuron when alone take certain dosage to the fresh weight inhibiting rate of target weeds the percentage as contrast; When Y Wei clomazone is alone take certain dosage to the fresh weight inhibiting rate of target weeds the percentage as contrast; Z be Acetochlor when alone take certain dosage to the fresh weight inhibiting rate of target weeds the percentage as contrast; E
0it during for ethoxysulfuron, clomazone, three kinds of pharmacy mix of Acetochlor, is the theoretical value of the percentage of contrast to target weeds fresh weight inhibiting rate; It when E is ethoxysulfuron, clomazone, three kinds of pharmacy mix of Acetochlor, is the measured value of the percentage of contrast to target weeds fresh weight inhibiting rate.
Evaluation criterion: work as E
0when-E>=10%, be expressed as synergistic effect, as-10% < E
0when-E < 10%, be expressed as summation action, work as E
0when-E≤-10%, be expressed as antagonism.
