Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of Synergistic herbicide compositions containing two careless ether and sulfonylurea, for preventing and treating paddy field weed.
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 two careless ether to the relevant composite product of ethoxysulfuron, cinosulfuron.

Application Example three: two careless ether and sulfonylurea control rice weed field control effectiveness test
Control medicament: the complex composition of two careless ether and sulfonylurea, produced by Shaanxi Welch Crop Protection Co., Ltd.'s research and development;
Contrast medicament: the two careless ether suspending agents (commercial) of 100 grams per liters;
15% ethoxysulfuron water dispersible granules (commercial);
10% cinosulfuron wetting powder (commercial).
If artificial weeding and clear water control treatment.
Using method: every mu be watered 30 liters after evenly cauline leaf sparge in each community
Spraying time: on July 21st, 2010, in the paddy rice 7-8 leaf phase, the field annual weed 1-3 leaf phase, carry out cauline leaf spraying 1 time.
Investigation method and drug effect are calculated
Investigation weeds object is: the weeds such as barnyard grass, cyperus iria, dayflower, difformed galingale herb, moleplant seed, investigate latter 15 days, 40 days strain preventive effects to weeds and the fresh weight preventive effect of 40 days.
Visual test medicament occurs without poisoning paddy rice.
Test results and analysis are respectively in table 9, table 10.
The table 9 pair careless ether ethoxysulfuron control paddy field weed test of pesticide effectiveness
The table 9 pair careless ether ethoxysulfuron composition for preventing and controlling paddy field weed test of pesticide effectiveness
Two careless ether and ethoxysulfuron have good control efficiency to paddy rice barnyard grass, cyperus iria, dayflower as shown in Table 9, preventive effect is better than single dose preventive effect, with contrast medicament, artificial weeding, with respect to significant difference between the rate of growth of clear water control treatment, and there is good quick-acting and lasting effect, in this experimental drug scope, to rice safety.
The table 10 pair careless ether cinosulfuron control paddy field weed test of pesticide effectiveness
The table 10 pair careless ether cinosulfuron built composition for preventing and controlling paddy field weed test of pesticide effectiveness
Two careless ether and cinosulfuron is composite that paddy rice barnyard grass, difformed galingale herb, moleplant seed are had to good control efficiency as shown in Table 10, preventive effect is better than single dose preventive effect, with contrast medicament, artificial weeding, with respect to significant difference between the rate of growth of clear water control treatment, and there is good quick-acting and lasting effect, in this experimental drug scope, to rice safety.
