Abstract
The invention relates to a penoxsulam and cyclosulfamuron herbicidal composition. The composition comprises the following ingredients by weight percent: 0.01-20% of an active component penoxsulam, 0.1% to 30% of an active component cyclosulfamuron and the balance of pesticide adjuvant. The penoxsulam and cyclosulfamuron herbicidal composition has the advantages that the herbicidal effect is improved after penoxsulam and cyclosulfamuron are compounded, resistance risks resulted from single use of penoxsulam or cyclosulfamuron is reduced, toxicity is low, residue is low, the use amount of a pesticide, use frequency of the pesticide and use cost are obviously reduced, higher effect of the composition is obviously higher than that of a single dose. The penoxsulam and cyclosulfamuron herbicidal composition is a good novel composition pesticide for preventing and controlling annual grassy weeds in a paddy field at present.
Description
Technical field
The invention belongs to agricultural chemicals weeding technical field, be specifically related to a kind of Herbicidal composition for rice field that penoxsuam, AC322140 be active ingredient of take, for preventing and kill off paddy field annual weed.
Background technology
Along with people improve constantly the requirement of food security, environmental protection, the agricultural chemicals service condition on the crops that people depend on for existence also receives much concern.Along with progressively eliminating of high-toxic pesticide, need efficient, low toxicity, safety, environment amenable pharmaceutical preparations.Meanwhile, the long-term use of agricultural chemicals makes developing immunity to drugs of disease pest and weed, also more and more higher to the requirement of control medicament, and this just needs agricultural chemicals research staff to develop the pharmaceutical preparations of highly effective and safe, meets control requirement.Because China's agricultural chemicals initiative is at the early-stage, the pesticide species with independent intellectual property right can't be satisfied the demand, so the pesticide mixed preparation of development of new, is the only way of current Agrochemicals.
Paddy rice is one of main cereal crops of China, and paddy field weeding is a great problem on producing.Chemical method weeding is the Main Means of controlling weeds.In recent years, because some weed killer herbicide kind large area are used separately, caused a lot of weeds to develop immunity to drugs.Therefore, be badly in need of the rice weeding pharmaceutical preparations of efficient, low toxicity, economy, safety.
Penoxsuam is rice field broad-spectrum herbicide, can effectively prevent and kill off barnyard grass, moleplant seed and annual sedge weed, and effective to numerous broad leaved weeds, and the lasting period is long.Meanwhile, it also can prevent and kill off anti-bensulfuron-methyl weeds in rice field, and many broad-leaveds and sedge weed and barnyard grass etc. are had to residual activity, is the widest kind of herbicide spectrum in weed killer herbicide for current rice field.But penoxsuam is strong inhibitor of acetolactate synthetase, medicament presents slower, needs certain hour weeds just dead gradually.
AC322140 is a kind of efficient sulfonylurea optional water field herbicidal, can be in water diffusion rapidly, after the root absorption of weeds, be transmitted in plant body hindered aminoacid synthetic.Promptly suppress the growth of weeds leaves and stems and the stretching, extension of root, then completely withered.To rice safety.Better to control efficiency such as barnyard grass, broad leaved weed, sedge weeds, undesirable to other grassy weed effects such as moleplant seed, lady's-grass.
Weed killer herbicide is rationally composite is to improve preventive effect, delays the speed of shift of weed community, reduces the resistance risk that the single use of agricultural chemicals brings, and alleviates the pollution to environment, reduces a kind of effective ways of use cost and reduction herbicide residue.The inventor conducts in-depth research being mixed of penoxsuam, AC322140, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that penoxsuam, AC322140 are mixed, within the scope of certain mixed ratio, paddy field weed is shown to obvious synergistic effect, after further study, completed the present invention.
Being mixed and applying of penoxsuam and AC322140 there is no report at present.
