Description
Technical field
The present invention relates to a kind of weed killer herbicide and using method thereof that contains organic compound, relate in particular to the compound herbicide and the using method thereof that contain multiple different organic compounds.
Background technology
Along with the development of agriculture applied technology, the paddy rice Planting Patterns is transplanted to drought by the water seedling in past and is educated floppy disk and throw and to plant, and develops into current paddy seeds and directly broadcasts sowing (live).At present, the cultivated area in live field is on a grand scale and increases fast, is example with the Hunan, and according to incompletely statistics, the live field area in Hunan has accounted for 76%, indivedual areas even reach 100%.The technical problem that the live owner of farmland will exist is that live seed and the weed growth in the rice field almost takes place simultaneously, utilizes the principle of rice shoot and weeds leaf age difference carrying out weeding to be difficult to be suitable for originally.The direct seeding fields herbicidal of a current characteristic of stock only works the effect of preventing and kill off to weeds before the bud, and the weeds of the leafing of partly having germinateed are not had preventive effect; Or only the weeds cauline leaf that has grown is worked, the while produces negative influence to the germination seedling of seed sprouting again.Therefore, take into account preceding weeds of not only anti-bud but also anti-cauline leaf weeds, and not influence the safety of live rice shoot, develop so a kind of weed killer herbicide current agricultural production is just had crucial meaning.
At present, the pyrazosulfuron of one-component belongs to sulfonylurea herbicide, and it is a selectivity inner sucting conduction type weed killer herbicide, mainly is absorbed by root system, can shift rapidly in weeds plant body after the absorption, suppresses growth, makes weeds dead gradually.Paddy rice can be decomposed this medicament, therefore to almost not influence of paddy growth.The effect of herbicides of this component is stable, and safe, the lasting period reaches 25～35 days.But because pyrazosulfuron is to late rice japonica rice relative with glutinous rice responsive (late rice kind intermediate keng rice and glutinous rice almost account for whole late rice kind less than 1%, and the overwhelming majority is a long-grained nonglutinous rice), above-mentioned strain weeds prevent and kill off Ying Shenyong.
The one-component cyhalofop-butyl of current use is the only kind that paddy rice is had tight security in the fragrant phenoxy propionic acid class weed killer herbicide, inhale the conductivity weed killer herbicide in belonging to, it is mainly absorbed by the blade and the leaf sheath of plant corpus, the phloem conduction accumulates the meristem zone in plant corpus, resists acetyl-CoA carboxylase (ACCase), fatty acid is synthesized to be stopped, the growth division of cell can not normally be carried out, and film system etc. contains the fat structural deterioration, causes plant death at last.Cyhalofop-butyl only works to the weeds that grown, though for malignant weeds such as gold, barnyard grass grass special efficacy is arranged, for not growing out in early days but a period of time just grows behind medicine, the same problem of preventing and kill off that exists.If the malignant weed before also difficult these buds of control of pyrazosulfuron, that can only live 20～30 days to paddy rice booting early stage during this period of time in, once mend anti-to the part malignant weed of not controlling.In addition, cyhalofop-butyl is big to aquatic arthropods toxicity, therefore should avoid flowing into the aquaculture place.
Not only cost is higher for the weed killer herbicide of above-mentioned any one one-component of use separately, and the grass spectrum is narrow extremely, be difficult to reach the effect of once preventing and kill off multiple weeds, and it is loaded down with trivial details to use program, takes time and effort.If use the weed killer herbicide comprise above-mentioned two kinds of active components simultaneously, definite key factor that just becomes the influence technique effect of Pei Fang selection and proportioning then.The active component that the composite herbicide that uses in the prior art is selected is more, so not only preparation difficulty, and also cost is higher, and herbicidal effect lacks specific aim; The prescription DeGrain that the part composite herbicide is also arranged, the composition of prescription are still waiting to improve and optimize.
