Abstract
The invention relates to a pesticide composition containing bispyribac-sodium. The pesticide composition is characterized in that: the pesticide composition comprises 1-50% of an active component A bispyribac-sodium, 1-70% of an active component B, an assistant, and the balance an excipient, wherein the active component B is selected from isoproturon and fluoroglycofen-ethyl; and the pesticide composition is prepared into a wettable pulvis, a water dispersed granule, a suspending agent, a suspended emulsion, a micron emulsion, and an emulsion in water. The pesticide composition of the invention can be used for controlling weeds in the paddy field.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of composition pesticide containing two careless ethers, 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.
Two careless ethers (bispyribac-sodium), molecular formula: C

4naO
8, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of chemical name: 2,6-.Two careless ether belongs to benzoic acid herbicide, this product is absorbed and is suppressed sour synthesizing of vinegar milk and hindered aminoacid biosynthesis side chain by root leaf. and be selective herbicide, use rice direct-seeding Tanaka, efficiently, wide spectrum, consumption are extremely low, after this product dispenser, can be absorbed by the cauline leaf of weeds very soon, and conduct to whole plant, suppress the growth of plant meristematic tissue, thereby kill weeds.
Isoproturon (isoproturon), molecular formula: C12H18N2O, chemical name: 3-(4-isopropyl phenyl)-1,1-dimethyl urea, isoproturon this product is dry land herbicide.There is special efficacy to preventing and kill off hard grass, net grass, amur foxtail etc., herbicidal effect good stability, herbicide wide spectrum, the optimum period for applying fertilizer is wide, high to crop safety, and toxicity is low, to person poultry safety, easy to use.
Fluoroglycofen-ethyl (fluoroglycofen-ethyl); molecular formula: C18H13ClF3NO7; chemical name: O-[5-(the chloro-p-toloxyl of the chloro-a-a-a-tri-of 2-)-2-nitro benzoyl] hydroxyl ethyl acetate, this product is new and effective diphenyl ether beans field herbicide after seedling.After it is absorbed by plants, make protoporphyrin oxidase suppressed, generate the virose tetrapyrrole of plant cell tool, gather and have an effect.It has, and speed of action is fast, activity is high, do not affect the features such as second stubble crop.Can effectively prevent and kill off the multiple broad leaved weeds such as Chenopodiaceae, polygonaceae, three-coloured amaranth, Siberian cocklebur, black nightshade, kitchen garden, dayflower, setose thistle.
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 isoproturon, fluoroglycofen-ethyl.

Control medicament: the complex composition of two careless ether and fluoroglycofen-ethyl, 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;
10% fluoroglycofen-ethyl missible oil (commercial).
If artificial weeding and clear water control treatment.
Using method: every mu be watered 35 liters after evenly cauline leaf sparge in each community
Spraying time: in the paddy rice 4-6 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, Paspalum distichum, needle spikesedge herb, investigate latter 10 days, 30 days strain preventive effects to 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 10.
The table 10 pair careless ether fluoroglycofen-ethyl control paddy field weed test of pesticide effectiveness
The table 10 pair careless ether fluoroglycofen-ethyl built composition for preventing and controlling paddy field weed test of pesticide effectiveness
Two careless ether and fluoroglycofen-ethyl is composite that the weeds such as paddy field barnyard grass, Paspalum distichum, needle spikesedge herb 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.
