Description
Technical field
The present invention relates to a kind of composite Herbicidal combinations, relate in particular to and a kind of penoxsuam, bentazone and methoxone or derivatives thereof are carried out ternary built, are 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 in the world comprises the almost population in whole East Asia and Southeast Asia, all is food with rice, produces each continent that spreads all over except the South Pole.Eighties of last century late period, about 4,000 hundred million kilograms of world's rice annual production average out to, about 1.45 hundred million hectares of cultivated area.Also be most important cereal crops in China paddy rice.China's rice growing face accounts for 1/4 of national cereal crops, and annual about more than 3,500 ten thousand hectares, output then accounts for over half.No matter cultivated area and output all rank first in China cereal crops.
The rice field of all rice workspaces of China always has a large amount of weeds to take place.Paddy rice all has plantation in China various places, and the weeds in paddy field kind is a lot, and various places are because of factor weeds kind differences such as weather, soil.According to statistics, kind surplus the weeds that national rice field can form harm have 200, wherein the most common, take place general, harm is serious have 40 surplus kind.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, accounting 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 paddy rice cultivated area.It is maximum with harm with the barnyard grass grass area to take place in these weeds, also have the hazard area utmost point orders of severity such as difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed, pondweed, Monochoria korsakowii to take second place, 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. in addition that various places are common.
Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.
Use weed killer herbicide behind the seedling that penoxsuam system is developed by U.S. Tao Nongke company (Dow AgroSciences), it causes effect by inhibition acetolactate synthestase (ALS).On September 24th, 2004 is in U.S. EPA official register registration, applies in southern US rice district in 2005, registers in China in 2008.This medicament can very effectively be prevented and kill off the barnyard grass grass and (comprise Stam F-34, the barnyard grass 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 the paddy field, and many broad-leaveds and sedge weed and barnyard grass grass etc. had residual activity, for present paddy field is composed the widest kind with killing grass in the weed killer herbicide, but use cost height, limiting its large tracts of land promotes the use of, therefore penoxsuam and other kind combinations of herbicides is composite, improve drug effect, enlarge the control of weeds spectrum, reduce usage amount, enlarging using of this medicament is present urgent problem.
