The activity of weeding of ring sulphur ketone is showed through base phenylacetone vinegar dual oxide enzyme (HPPD) inhibitor by 4-, 4-} base phenylacetone vinegar dual oxide enzyme (HPPD) inhibitor is a kind of huge legendary turtle compound, Fe (II) cation can be wrapping to show activity in 4-base phenylacetone vinegar dual oxide enzyme (HPPD) ion cluster by it, as taken HPPD as the a-ketone acid compound of basic structure.Its activity of weeding not only shows that organic molecule body is inner, but also shows other outsides in nature, and ring sulphur ketone also has good absorption, transport and metabolic stability (particularly weeds) in plant corpus.
Ring sulphur ketone is mainly used in multiple grassy weed and the broad leaved weed of preventing and kill off corn field and paddy Tanaka, it can be prevented and kill off cross spectrum weeds, mainly 1 year genus setaria and wild multitude belong to weeds, also obstinate broad leaved weed can effectively be prevented and kill off, as glyphosate tolerant class, the phthalein of resistance to second lactic acid synthetase inhibitors class, resistance to dicamba class weeds.
Ring sulphur ketone compared with the advantage of other kinds is: have very strong killing action to multiple weeds, noresidue is active, have stronger ability to resist splash erosion, and herbicidal spectrum is wide, effectively can prevents and kill off the weeds such as Cirsium, japanese bearbind genus, Veronica, smallflower galinsoga herb genus, honor fiber crops genus, yellow chamomile and clearvers.Ring sulphur ketone can all keep good activity of weeding in the vegetative period that crop is whole, carries out good prevention and control, and can not work the mischief to next batch of crops such as soybean to broad leaved weed.
Herbicide carryover:
The super-high-efficient medicaments such as sulfonylurea herbicide metsulfuron-methyl, chlorine sulphur are grand, under the conventional operation technique of wheat paddock, medicament can remain even several years several months in soil, to succession crop corn, rape, cotton and some legume generation poisoning in various degree, even dead.Happen occasionally [12] at the herbicide carryover of China's persistent sulfonylureas, so that the provinces and cities such as Henan, Sichuan forbid selling and use the grand and mixture preparation of metsulfuron-methyl, chlorine sulphur at present.Sulfonylurea herbicide selectivity is strong, very large to the sensitivity differences of Different Crop, such as, cotton is the most responsive to metsulfuron-methyl, corn is taken second place, paddy rice and rape then drug resistance are comparatively strong, and the residual activity of sulfonylureas is relevant with formulation rate, soil pH value, the content of organic matter, temperature, soil moisture and spraying time and the chemical constitution of weed killer herbicide own etc.Nineteen ninety-five once there is the major accident of the grand Polluted Paddy of green sulphur in Shenyang, caused nearly 533.4 hectares of rice fields to be injured, wherein 267 hectares of total crop failures; Within 1992, in the wheatland of Hebei, use metsulfuron-methyl, also cause the poisoning of rear stubble corn large area; The residual mainly Conjugate polyamines of sulfonylurea herbicide, Conjugate polyamines is often considered to a kind of detoxification mechanism of agricultural chemicals, but Recent study finds, green sulphur is grand can be discharged with the form of parent compound or its metabolite under certain conditions once again.In a word, the leaching of extractable residue migration is more weak, and has inhibitory action to the growth of succession crop, can produce poisoning when reaching doses to succession crop.
Pesticide resistance:
Sulfonylurea herbicide listing shortly has the report developed immunity to drugs to weeds, 1987, and the thorn lettuce of Idaho State winter wheat just mixture that is grand to green sulphur and metsulfuron-methyl creates resistance, and expands rapidly 13 states and Canadian 1 state to.So E.I.Du Pont Company announces green sulphur must not be used grand to protect the valuable weed killer herbicide of this class in the U.S. 7 states, and strengthens the research work [14] to sulfonylurea herbicide resistance.Applying sulfonylurea herbicide after 10 years, finding that chickweed, perverse lettuce, summer cypress, spire salsola collina, Annual Ryegrass, perennial rye create resistant biotypes in the U.S..Wheatland, to apply green sulphur from 1984 grand in Australia, and after wheat uses 8 years continuously, volume stem knotweed, common sow thistle, garlic mustard are grand to green sulphur, metsulfuron-methyl, thiameturonmethyl create resistance.
Mechanism of action and the sulfonylurea herbicide of sulfonamides herbicide are similar, are typical inhibitor of acetolactate synthetase.But selective difference is large, kindred plant is very not large to the sensitivity differences of sulfonamides herbicide, and as Flumetsulam rapid metabolization in milpa, only 2 hours its half life period, the half life period in weeds Amaranthus retroflexus body then reaches 104 hours.
The control efficiency of different weed killer herbicides to different weeds has different, crop Tanaka weeds kind is many, want well control more difficult, single drug also can cause field grass to change mutually simultaneously, how to develop efficient combination thing for careless phase change is future directions, good drug efficacy, the demand that control spectrum is wide, resistance is development slowly.
For these reasons, invent a kind of novel herbicidal composition, just seem particularly necessary.
