Abstract
The invention provides a herbicide composition which comprises the following active ingredients: bentazone and diflufenican. The invention also provides preparation prepared by the herbicide composition, and the application thereof. In the invention, the bentazone and the diflufenican which have different structure types and action mechanisms are compounded for use, so that the preventing and removing effects of the two components for annual and perennial gramineous weeds and broadleaf weeds of a soybean field, a wheat land, a paddy field and a pea field are effectively improved; and simultaneously, when the two components are respectively used as a single component, the herbicidal spectrum of the two components can be broadened.
Description
Technical field
The present invention relates to a kind of herbicidal composition and preparation thereof and application
Background technology
Bentazone is 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 decomposed by microorganism in soil after the dispenser.Be mainly used in preventing and kill off sedge family and broad leaved weed, its dosage is generally 50-1500g (a.i).
Diflufenican is used the medicine soil layer that can form anti-leaching at the soil table before and after weeds germinate, keep active in the crop whole growth phase.When weed germination all can absorb medicament by medicine soil layer young shoot or root system, this agent has the carotenoid of inhibition biosynthesis effect, carotenoid content descends in the weeds plant of absorption medicament, cause chlorophyll destroyed, membranolysis, weeds then show as young shoot decolouring or white, and whole strain is at last wilted dead.Most of broad leaved weed crop Tanakas such as wheat, paddy rice, some legume (as white plumage French beans and spring sowing pea), carrot, sunflowers.Its dosage is generally 100-1500g (a.i).
Summary of the invention
The purpose of this invention is to provide a kind of broad weed-killing spectrum, to the significant herbicidal composition of the control efficiency of crop weeds, described herbicidal composition preparation and application thereof also are provided.
The invention provides a kind of herbicidal composition, wherein, the active component of described herbicidal composition comprises: bentazone and diflufenican.
The present invention also provides according to herbicidal composition prepared preparation of the present invention.
The present invention also provides the application of above-mentioned preparation in control soybean field, wheat paddock, paddy field, the annual and perennial grassy weed in pea field and broad leaved weed.
The present inventor finds in research process unexpectedly, bentazone and the composite use of diflufenican that will have different structure types and mechanism of action, the property of medicine not only can not occur offsets or other side effects, also has obvious synergistic effect on the contrary, can improve these two kinds of components to a greater degree to the preventive effect of soybean field, wheat paddock, paddy field, the annual and perennial grassy weed in pea field and broad leaved weed, the grass that kills that has enlarged simultaneously when these two kinds of components are used as single component is composed.
Particularly, Herbicidal combinations of the present invention has the following advantages:
1, Herbicidal combinations of the present invention shows fabulous synergistic effect in certain ratio range, mixed composition has obviously improved herbicidal effect than its single agent, thereby reduced using dosage, when reducing peasant's drug cost, reduced the degree to environmental influence.
2, enlarged and kill the grass spectrum, a kind of medicament can be prevented and treated multiple weeds simultaneously, and a kind of means of prevention extremely easily and effectively is provided, and grass family and the broad leaved weed of soybean field, wheat paddock, paddy field all had good control efficiency.
3, Herbicidal combinations of the present invention is systemic herbicide and the combination of tagging property mixture of herbicides, and the medicament difference makes action characteristic obtain extremely strong mutual supplement with each other's advantages, can effectively delay generation and the development of single agent resistance.

In the greenhouse, adopt potted plant method to measure the preparation of composition and bentazone, diflufenican to the preventive effect of grass family and broad leaved weed.
Test method: the greenhouse pot culture method is adopted in test, the quantitative weed seed of sowing in Disposable paper cup, treat that the unearthed back of weeds 1.5-2 leaf carries out thinning during the phase, each dixie cup is cultivated by the more consistent weeds plant of 5 strain growing ways of selecting and remain, and regularly water N, P, the aqueous solution of K composite fertilizer, treat that grassy weed grows to the 3-4 leaf phase, broad leaved weed 4-6 leaf carries out the cauline leaf spraying with crawler type crop sprayer with the preparation of embodiment 1-29 and Comparative Examples 1-2 gained during the phase to be handled, each processed group dosing (being the effective active dose of components) is as shown in table 1, handle and to be placed on the greenhouse behind the back hour and to continue to cultivate and observe, if the clear water contrast, the herbicidal effect of each processing of " Invest, Then Investigate " in 20 days.The results are shown in Table 1.Herbicidal effect among the present invention (being the weeds preventive effects) is represented with the fresh weight preventive effect, can record as follows:
The weight of the weeds of each chemicals treatment group of weighing in 20 days and clear water control group is calculated its fresh weight preventive effect after dispenser, and computing formula is as follows:
Fresh weight preventive effect computing formula is:
Table 1
Imitating result of the test by last medicine administered to bring out the cold shows, it is more single with comparing weeds particularly to the broad leaved weed obvious synergistic effect after bentazone, diflufenican are used with, grassy weed also there is good synergistic effect, reaches the purpose of preventing and kill off grassy weed and broad leaved weed simultaneously.
Though above the present invention is described in detail with general explanation and embodiment, on basis of the present invention, can to do various modifications or improvement, this will be apparent to those skilled in the art.Therefore, these modifications or improvements all belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
