Abstract
The present invention relates to a herbicide composition, which comprises sulcotrione and at least one triazine herbicide. The present invention comprises the ingredients of the following proportion by weight of 1 share of sulcotrione and 100 shares of the triazine herbicide to 100 shares of sulcotrione and 1 share of the triazine herbicide on the basis of active ingredients, and the active ingredients in the composition has a weight percentage content of 0.5 to 95%; the triazine herbicide is atrazine, simazine, metribuzin, cyanatryn, prometryn, ametryn, etc., the herbicide composition of the present invention has obvious synergistic effects, and can be used for preventing and curing grassy weeds and broad-leave weeds.
Description
Technical field
The present invention relates to contain the herbicidal composition of weed killer herbicide material, relate in particular to the preparation of compositions and the application that contain sulphur humulone [chemical name is: 2-(2-chloro-4-formamide benzene formyl) cyclohexane-1,3-diketone] and triazine herbicide.
Background technology
At present China's corn field herbicide mainly contains the A Yi mixture of using before the seedling (atrazine+Acetochlor), use behind the seedling 2,4-D butyl ester, dicamba, Brominal, beautiful farming are happy etc.Because the longevity of residure of atrazine in soil is longer, be unfavorable for crop rotation, not only influence back stubble is planted brassicaceous vegetable, and to afterwards stubble is planted wheat, soybean also can produce poisoning, and it is bigger that the herbicidal effect of the weed killer herbicide of soil treatment is influenced by soil moisture, drug effect is relatively poor when arid, even invalid; And cauline leaf handles in the weed killer herbicide 2, and 4-D butyl ester, dicamba, Brominal etc. only have preventive effect preferably to broad leaved weed, and are invalid to grassy weed; Cauline leaf inorganic agent nicosulfuron all has preventive effect preferably to broad leaved weed and grassy weed, but in response to higher with cost, and influence its large scale application.
The sulphur humulone is the three ketones weed killer herbicide, but both native list processings before the seedling, but also cauline leaf spraying, instant effect simultaneously behind the seedling.Sulphur humulone residual life in soil, is short, so to succession crop safety.But use preventive effect and the weeding cost not satisfactory defective of fashion existence to grassy weed as single agent.Therefore, inventors of the present invention attempt carrying out the research work of the mixture preparation of sulphur humulone and other weed killer herbicides, in the hope of a kind of efficient, low-residual of further invention, low cost and to grass family and broad leaved weed the disposable herbicide composition of better preventive effect is arranged all, satisfy the needs of agricultural production.
Summary of the invention
The sulphur humulone (English common name: sulcotrione) chemical name: 2-(2-chloro-4-formamide benzene formyl) cyclohexane-1, the 3-diketone, structural formula is as follows:
" herbicide action target and new varieties initiative " (Su Shaoquan chief editor, Chemical Industry Press publish) reaches and " can find this medicament in the external pesticide species handbook new edition bound volume (the Ministry of Chemical Industry's agricultural chemicals central information facility is write)." agricultural chemicals " magazine the 40th volume the 7th phase (2001) 20～21 pages of preparation examples that this compound is provided.In order to satisfy the needs of agricultural production, further improve the herbicidal effect of sulphur humulone, reduce agricultural cost and raising to the safety of succession crop, the present invention proposes a kind of novel herbicidal composition, contain sulphur humulone and at least a triazine herbicide in the active component of said composition.
Have now found that the use that is mixed of sulphur humulone and triazine herbicide has extremely strong synergistic effect, not only can improve the preventive effect to grassy weed greatly, thereby and the using dosage that can also reduce the sulphur humulone reduce use cost.

Composition of the present invention can be used by common method, both can soil treatment, also but the cauline leaf spraying is handled, amount of application changes with weather condition, use bigger dosage during the weather arid, Soil Moisture can be used lower dosage well, and using optimum period is to carry out the cauline leaf spraying when weeds all sprout substantially behind the crop seedling to handle.Its lasting period is relevant with the content of single agent in the composition, also relevant with extraneous factor usually.
Composition of the present invention can be used for preventing and treating grass family and broad leaved weed, for example corn, sugarcane crop Tanaka's barnyard grass grass, lady's-grass, green foxtail, artemisiifolia, knotweed, lamb's-quarters, three-coloured amaranth, Siberian cocklebur, piemarker, field bindweed etc.
Composition of the present invention has five advantages: the one, improved the herbicidal effect of medicament.Said composition shows fabulous synergistic effect in certain ratio range.The 2nd, enlarged and killed the grass spectrum.Sulphur humulone list uses the herbicidal effect to broad leaved weed to be better than the grassy weed preventive effect, has improved the preventive effect of sulphur humulone to grassy weed after using with triazine herbicide greatly.Said composition all has preventive effect preferably to a large amount of main weeds that take place in field, belongs to the disposable herbicide composition, for the control of weeds of corn, sugarcane field provides a kind of medicament of chemical control comprehensively and effectively.The 3rd, reduced drug cost.Said composition can significantly reduce the using dosage of medicament in application, thereby has both reduced the influence degree to environment, obviously reduces Financial cost again.Single every mu of weeding cost of sulphur humulone 18-20 unit that uses uses every mu of weeding cost of above-mentioned mixture to reduce by 50%, only needs 9-10 unit.The 4th, improved safety to succession crop.Because reduced for example consumption of atrazine of triazine herbicide after the two is used with, thereby the corresponding residual activity of atrazine in soil that reduced improved the safety to succession crop.The 5th, can prolong service time of medicament.Owing to the mechanism of action difference of each single agent in the said composition, there is not the problem of cross resistance, so the application of sulphur humulone and triazine herbicide composition can delay generation and the development of drug resistance or pesticide resistance weeds, help to prolong the service time of medicament.
