Description
Technical field
The present invention relates to a kind of novel built Herbicidal combinations, particularly relate to a kind of ternary built, be applied to paddy rice, wheat, sugarcane, novel built Herbicidal combinations between corn field.
Background technology
Paddy rice is one of world's staple food crop, and nearly half population, is all food with rice in the world, produces throughout each continent except south, the arctic; 20 end of the centurys, View of World Rice annual production average out to about 4,000 hundred million kilograms, cultivated area about 1.45 hundred million hectares.One of cereal crops that rice in China is important, rice in China sowing area accounts for 1/4 of national cereal crops, about 3,500 ten thousand hectares every year, and output accounts for 50% of total grain output.No matter cultivated area or output, all ranks first in Grain in China crop.
The paddy field with water direct seeding or direct-sowing dry is economized in the rice field, particularly Zhejiang, Jiangxi, Jiangsu, Anhui etc. of all rice workspaces of China, all has a large amount of weeds to occur; Paddy rice all has plantation all over China, and weeds in paddy field is of a great variety, and rice district, various places weeds kind is different.According to statistics, the weeds that national rice field forms harm have more than 200 to plant, wherein the most common, endanger and heavier have more than 40 to plant.It is documented, crop smothering (2 ~ 5 grades) crop smothering area more than medium in national rice field reaches 1546.7 ten thousand hm
2, account for 46% of total cultivated area, (4 ~ 5 grades) area of wherein seriously causing harm is 3,800,000 hm
2, account for 11.5% of Monitoring of Paddy Rice Plant Area.According to Weed infestation statistics, barnyard grass occurring area and harm rank first, and are secondly difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed, pondweed, Monochoria korsakowii, ear leaf water amaranth etc.
Along with the development of agricultural cience and farming techniques and the enforcement of mechanization, live field (water direct seeding and direct-sowing dry) reduces planting patterns that the is artificial and amount of lightening one's labor, but more rely on the chemical weed control in later stage; The simultaneously propagation and employment of chemical herbicide, as saving of labor, save time, enforcement that one of the strong well stimulation that reduces costs supports new mode of heavily planting.
With weed killer herbicide after the seedling that penoxsuam system is developed by Tao Nongke company of the U.S. (Dow AgroSciences), it works by suppressing acetolactate synthestase (ALS).On September 24th, 2004, in the registration of U.S. EPA official register, applies in southern US rice district for 2005, within 2008, to register in China and starts to promote the use of.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, medicament, 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), it is documented the weeds of anti-sulfonylurea herbicide 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 there is obvious difference.Penoxsuam effectively can prevent and kill off barnyard grass (comprising the barnyard grass to Stam F-34, dichloro quinolinic acid and anti-acetyl coenzyme A carboxylase tool resistance) rice barnyard grass, angustifolia arrowhead herb, sesbania and annual sedge weed in defense sector; For producing the improvement of resistant weed in alternative paddy field to sulfonylurea.Therefore penoxsuam is the comparatively ideal weed killer herbicide of water prevention weeds in paddy field.
In the use procedure of field, although penoxsuam shows to mix to most of grass family such as barnyard grasses have good preventive effect, only only have some inhibitory action to part grassy weed, broad leaved weed, nutgrass flatsedge, a drug cannot solve the harm of weeds in field.。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.
Penoxsuam is water prevention rice field grass family and the comparatively ideal weed killer herbicide of part sedge weed in sum, but still have its weak point, based on above reason by penoxsuam and other herbicide for paddy field science assembly, thus expand herbicide spectrum, reducing times for spraying and dosage, is current rice district urgent need to solve the problem.
