Description
Technical field
The invention belongs to technical field of pesticide, weed killer herbicide field especially is specifically related to the ternary built Herbicidal combinations of a kind of bentazone, methoxy miaow nicotinic acid and Quizalotop-ethyl.This Herbicidal combinations can be applicable to soybean field postemergence weed control.
Background technology
Bentazone has another name called Lysimachia sikokiana pellet, Bentazon.Chemical name: the 3-isopropyl-(1H)-and benzo-2,1,3-thiadiazine-4-ketone-2, the 2-dioxide, structural formula is:
This weed killer herbicide is an optionally herbicide after seedling of contact killing type tool, is used for cauline leaf processing in seedling stage, works by the blade contact.Dry land is used, and is transmitted to by the blade face infiltration earlier and suppresses photosynthesis in the chloroplast.The paddy field is used and can be absorbed by root again by the blade face infiltration, is transmitted to cauline leaf, hinders weeds photosynthesis and water metabolism strongly, causes nutrition hunger, makes physiological function lack of proper care and cause death.Active ingredient is detoxified to active weak glycoconjugates metabolism in the tolerable crop body, and to crop safety, 6-18 week bentazone can be by microbial decomposition in soil after the dispenser.But bentazone is invalid to grassy weed, and herbicidal spectrum is single.
Quizalotop-ethyl has another name called smart quizalofopethyl, the spirit of lid grass.Chemical name: (R)-2-[4-(6-chloro-quinoxaline-2-base oxygen) phenoxy group] ethyl propionate, structural formula is:
Quizalotop-ethyl is the highly finished product removed inactive optical isomer (L-body) in the process of synthetic quizalofopethyl after.Its mechanism of action absorbs by the weeds cauline leaf, and two-way up and down conduction is accumulated in top and intercalary meristem in plant corpus, and it is synthetic to suppress cell fatty acid, makes the weeds necrosis.Smart quizalofopethyl is the optionally novel dry land cauline leaf of an a kind of high speed inorganic agent, and the selectivity of height is arranged between grassy weed and dicotyledonous crops, and the grassy weed on the broad leaf crop is had good preventive effect.Smart quizalofopethyl improved by plant absorbing and in plant mobility, so speed of action is faster, drug effect is more stable, is not subject to the influence of environmental conditions such as rainwater, temperature and humidity, and is environmentally safe.But because Quizalotop-ethyl is used in the soybean field for a long time, some weeds have produced serious resistance to it.
Methoxy miaow nicotinic acid (acifluorfen-sodium), other titles: golden beans; Chemical name: (RS)-2-(4-isopropyl-4-methyl-5-oxygen-2-imidazoline-2-yl)-5-methoxy Nicotinicum Acidum.Be a kind of imidazolinone herbicide, its structural formula is:
Methoxy miaow nicotinic acid is mainly used in soybean field and peanut field postemergence weed control. can prevent and kill off most of grassy weeds, broad leaved weed and nutgrass flatsedge. and broad leaved weed adds piemarker, admire amaranth Lay, field mustard, lamb's-quarters, bur beggar-ticks, clearvers, morning glory, benbie, field forget-me-not, knotweed, black nightshade, Veronica etc.; Grassy weed and sedge weed such as wild oat, bromegrass, annual bluegrass, moleplant seed, millet, amur foxtail, thin and delicate lady's-grass, common rush, Chufa etc.But methoxy miaow nicotinic acid residual in the soil has certain key to succession crop, and therefore, succession crop is longer interval, and for example be 12 months the interval of beet, rape.So, want the strict consumption of controlling methoxy miaow nicotinic acid in the use.
Soybean field herbicide is limit by crop safety at present, it is also limited to kill the grass spectrum, be used alone the agent of weed killer herbicide list and can not control the generation of soybean weeds completely effectively, moreover some weed killer herbicide is because water-soluble big or the field lasting period is oversize, consumption is excessive or the inhomogeneous residual hazard that all causes easily this season crop or succession crop of dispenser.Therefore, the present invention selects to kill grass spectrum difference, being made into mixture after the bentazone of pluses and minuses complementation, methoxy miaow nicotinic acid and the suitable decrement of Quizalotop-ethyl three all weed killer herbicides uses, so both enlarged and killed the grass spectrum, obviously improved herbicidal effect, also avoided this season is done the deposits yields poisoning and succession crop produced the possibility of residual hazard.
