Description
Technical field
The present invention relates to a kind of complex herbicidal composition, particularly relate to and a kind of penoxsuam, bentazone and methoxone or derivatives thereof carried out ternary built, be applied to the novel built Herbicidal combinations of paddy field.
Background technology
Paddy rice is one of world's staple food crop, and nearly half population, comprises the population in almost whole East Asia and Southeast Asia in the world, is all food with rice, produces throughout each continent except the South Pole.Eighties of last century late period, View of World Rice annual production average out to about 4,000 hundred million kilograms, cultivated area about 1.45 hundred million hectares.Also be most important cereal crops in China paddy rice.China's rice growing face accounts for 1/4 of national cereal crops, and every year about more than 3,500 ten thousand hectares, output then accounts for over half.No matter cultivated area and output, all ranks first in China cereal crops.
The rice field of all rice workspaces of China, always has a large amount of weeds to occur.Paddy rice all has plantation in China various places, and weeds in paddy field kind is a lot, and various places are because of the factor such as weather, soil weeds kind difference.According to statistics, the weeds that national rice field can form harm have more than 200 to plant, wherein the most common, occur general, endanger and serious have more than 40 to plant.According to investigations, crop smothering area of (2 ~ 5 grades) crop smothering more than medium in national rice field reaches 1546.7 ten thousand hm
2, account for more than 46% of total cultivated area, (4 ~ 5 grades) area of wherein seriously causing harm is 3,800,000 hm
2, account for more than 11.5% of Monitoring of Paddy Rice Plant Area.Maximum with harm with barnyard grass occurring area in these weeds, also have the hazard area pole orders of severity such as difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed, pondweed, Monochoria korsakowii to take second place, what various places were common also has water silk floss, duckweed, Chinese scholartree leaf duckweed, little najas marina, short arrowhead, eel grass, bent grass, Herba Cyperi Glomerati, firefly Lin, water pepper, alternanthera philoxeroides, water three-coloured amaranth, hornwort, Eclipta prostrata, Sculellaria barbata etc.
Along with the development of agricultural cience and farming techniques, chemical herbicide apply as saving of labor, save time, one of cost-effective strong well stimulation.
With weed killer herbicide after the seedling that penoxsuam system is developed by Tao Nongke company of the U.S. (Dow AgroSciences), it causes effect by suppressing acetolactate synthestase (ALS).On September 24th, 2004, in the registration of U.S. EPA official register, applies in southern US rice district, within 2008, registers in China for 2005.This medicament very effectively can be prevented and kill off barnyard grass and (comprise Stam F-34, the barnyard grass of dichloro quinolinic acid and anti-acetyl coenzyme A carboxylase tool resistance), moleplant seed and annual sedge weed, simultaneously, it also can prevent and kill off anti-sulfonylurea weeds in paddy field, and to many broad-leaveds and sedge weed and barnyard grass etc., there is residual activity, for the kind that herbicide spectrum in current paddy field weed killer herbicide is the widest, but use cost is high, limit its spread to use, therefore by penoxsuam and other kind combinations of herbicides composite, improve drug effect, expand control of weeds spectrum, reduce usage amount, expanding using of this medicament is current urgent problem.
The English common name penoxsulam of penoxsuam, chemical name 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) triazole-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN).Structural formula is:
Penoxsuam is a kind of triazolopyrimidine sulfonamide weed killer herbicide, and by suppressing acetolactate synthase to work, medicine, via grass cutting blade, sheath portion or root absorption, conducts to meristematic tissue, causes weed growth to stop, yellow, then dead.For preventing and kill off paddy field annual weed, to barnyard grass special efficacy, but to the anti-heterodyne of part grassy weed, nutgrass flatsedge and broad leaved weed.The action target of this medicament is acetolactate synthestase (ALS), according to the hodgepodge of the anti-sulfonylurea herbicide of reported literature to the cross resistance level of triazolopyrimidine sulfonamides herbicide significantly lower than to other sulfonylurea medicaments, and the activity of weeding of penoxsuam and other ALS inhibitor have obvious difference.Therefore penoxsuam is the comparatively ideal weed killer herbicide of water prevention weeds in paddy field.
In actual use, penoxsuam weeding has broad spectrum activity, and to the barnyard grass of rice field, a thousand pieces of gold of low age and annual nutgrass flatsedge, and anti-sulfonylurea broad leaved weed is all effective, to barnyard grass special efficacy, but not satisfactory to part grassy weed, broad leaved weed, nutgrass flatsedge preventive effect.In addition, penoxsuam has used nearly 10 years in South Rice Region of China, by initial consumption (active ingredient) 15g/hm
2be increased to present 37.5g/hm
2.Although temporarily have no about the document of weeds to penoxsuam resistance, in actual production, consumption has improved 2-2.5 doubly, and the coming years, consumption will improve again, and concern resistance weed is very important problem.
