Abstract
The invention relates to a penoxsulam-amidosulfuron weeding composition. Active ingredients of the weeding composition comprise penoxsulam and amidosulfuron. According to weight percentage, the weeding composition comprises 0.05%-30% of the penoxsulam, 0.1%-30% of the amidosulfuron and the balance of pesticide adjuvants. The weeding composition has the advantages that the weeding effect is improved after the penoxsulam is compounded with the amidosulfuron, the resistance risk caused by independently using the penoxsulam or the amidosulfuron is reduced, low toxicity and low residue are realized, the dosage, the use times and the use cost are obviously decreased, and the effect of the composition is obviously superior to that of each single dosage. Therefore, the penoxsulam-amidosulfuron weeding composition is a good novel composite reagent for controlling annual weeds in paddy field.
Description
Technical field
The invention belongs to agricultural chemicals weeding technical field, be specifically related to a kind of Herbicidal composition for rice field taking penoxsuam, amidosulfuron as active ingredient, 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, and the therefore 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.
Amidosulfuron is a kind of efficient sulfonylurea selective herbicide, and active ingredient can diffusion rapidly in water, is transmitted in plant body hindered aminoacid synthetic after the root absorption of weeds.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 the mixture of penoxsuam, amidosulfuron, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find that penoxsuam, amidosulfuron carry out mixture, within the scope of certain mixed ratio, paddy field weed is shown to obvious synergistic effect, after further study, completed the present invention.
The mixture of penoxsuam and amidosulfuron and application there is no report at present.
