Description
Technical field
The present invention relates to a kind of herbicide synergist.
Background technology
From 2, since 4-dripped and brings into use in nineteen forty-six, the existing 60 years of development histories of weed killer herbicide industry had successfully been developed large quantities of selective herbicides so far.Weed killer herbicide is reliable, the most most economical means in the farmland weeding technology as the important component of modern agriculture production system.Current, it is main with selective herbicide still that the weeds of staple crops are administered, and still owing to the use repeatedly of the identical weed killer herbicide of the mechanism of action, causes the weeds population that weed killer herbicide has been produced pesticide resistance.Therefore, following weed killer herbicide should be towards efficient, low toxicity, can prevent and treat resistant weed and be difficult for causing that the direction of environmental problem develops.
The weed killer herbicide of now having found regardless of its chemical constitution, all is through the weeding effect is brought into play in the effect of crucial target.So far, fixed weed killer herbicide target is about 15 kinds, and wherein, the molecular target that plays an important role has 2 kinds, i.e. proporphyrinogen oxidase (protox) and acetolactate synthestase (ALS).Since nineteen ninety-two, achievement is to confirm HPPA dioxygenase (HPPD) the most significantly in the study on mechanism of weed killer herbicide, and many weed killer herbicides all are to show significant activity of weeding through the target gene HPPD that suppresses in the plant corpus; Each weed killer herbicide all has its corresponding target gene; Up to the present, found that many targets are different from the action target of existing commercial weed killer herbicide, regrettably; People still understand seldom the character at responsive target position in the relevant plant corpus at present; For example, the result shows to the arabidopsis gene group analysis, and 1000 several genes are arranged in the arabidopsis body.And theoretically, each gene all can be used as the potential target of weed killer herbicide in the plant corpus, and problem only is whether their inhibition be enough to cause that plant growing stops, metabolism is obstructed and accumulation takes place the toxin intermediate and cause weeds withered.
Obviously visible thus, when using weed killer herbicide in the farmland, how high no matter used the selectivity of weed killer herbicide have, when weed killer herbicide is poisoned weeds with poison, all can more or less damage cultivated when stubble crops; Or the residue of weed killer herbicide infringement succession crop; Especially found in 1970 to have had been found that more than 200 kind of weeds have resistance since the resistance of weeds to weed killer herbicide, weeds increase the resistance of weeding year by year; Force peasant household to increase the working concentration of weed killer herbicide year by year; Increase its consumption, this further damages crops again, reduces the output of crops.Here it is, and as you know use weed killer herbicide is actually a weeding and do not increase production.
Butachlor and benthiocarb are that China produces tonnage number maximum, use the most general weed killer herbicide, and the barnyard grass grass has obvious resistance to these two kinds of weed killer herbicides; And resistance level has obvious enhancing from north to south; Double rice cropping system barnyard grass grass resistance is greater than single cropping rice producing region, and service time is long more, and resistance is high more.And after the weed killer herbicide concentration of using increases, remove to when the stubble crops with after the poisoning of batch crops, also can bring harm to farmland on every side.For example: 2; Weed killer herbicides such as 4 d butyl esters, 2 first, 4 chlorine sodium in application because the droplet that forms is tiny, temperature is too high, relative air humidity is excessive, wind-force is too small, illumination is strong excessively, nozzle position apart from ground or the blade face too high; Liquid pump pressure is excessive etc.; All be prone to cause the droplet volatilization, the drift action after the droplet vaporization can make contiguous sensitive crop that is involved and trees etc. suffer poisoning in various degree.Like 2.4 d butyl esters, can far to reach 2000～3000m far away for droplet drift when spraying on ground; Use trefanocide, dogstail top grade weed killer herbicide, drift sometimes can reach 5000m at most.This type of poisoning incident once repeatedly took place in various places, used the concentration of weed killer herbicide big more, and the frequency that this type poisoning takes place and the degree of harm are also big more.
Summary of the invention
One of the object of the invention is to provide a kind of herbicide synergist, improves the activity of weed killer herbicide, the consumption of weed killer herbicide is reduced, thereby reduce weed killer herbicide to crops and the harm of sensitive crop on every side.
In order to solve the problems of the technologies described above; Herbicide synergist of the present invention; Formed by plant steroid compounds and solvent, plant steroid compounds is selected from a kind of in methylsterol, cupreol, campesterol, ergosterol and the brassicasterol and more than one; Solvent is that in the fatty acid of C10～C24 one or more mix perhaps one or more mixing in cottonseed oil, palm oil, the soybean grease.
Result of the test shows; The herbicide synergist of patent of the present invention; Can improve the activity 30～80% of weed killer herbicide, make the consumption of weed killer herbicide reduce 30～80%, thereby reduce weed killer herbicide crops and the harm of sensitive crop on every side; Increase crop yield, and reduce the pollution level of weed killer herbicide environment.The mechanism of the synergistic effect of herbicide synergist of the present invention is also uncertain, still, can be that the plant steroid compounds in the synergist of the present invention can promote plant root growth certainly, and helps chlorophyllous synthetic.
As the preferred embodiment of technique scheme, the percentage by weight of said plant steroid compounds and solvent is 5～40%: 60～95%.
Another object of the present invention is to provide a kind of herbicidal composition, mix by above-mentioned herbicide synergist and the former medicine of weed killer herbicide.The former medicine of said weed killer herbicide is make a din a kind of in ketone, pyrimidine salicylic acid, aryloxy group benzene chlorine propyl ester class, carbamates, benzoic acids, phenoxy carboxylic acid, organic phosphates or the phthalmide weed killer herbicide of triazine, dinitroaniline, sulfonamides, diphenyl ether, dinitro benzene, cyclic ethylene ketone, substituted urea class, nitrile, pyridines, bipyridyliums, sulfonylurea, miaow.
