Abstract

The present invention relates to an agricultural chemical synergistic auxiliary agent which is prepared from a tween surface active agent, an N-R-2-pyrrolidone compound and a commonly-used agricultural chemical solvent (if necessary), wherein the substituent R of the pyrrolidone compound is H or C1-12 alkyl. The agricultural chemical synergistic auxiliary agent can be used cooperatively with various agricultural chemicals for desinsection, sterilization, weed removal, growth regulation, etc.

Description

Agricultural chemicals synergist
What the present invention relates to is the Chemical composition that is used to improve pesticide controls such as desinsection, sterilization, weeding, plant growth regulating or result of use.
With the insecticide pesticide is example, for a long time, owing to use chemical pesticide in a large number year after year, causes pest to produce pesticide resistance in various degree.Simultaneously, data report is arranged also,, make the normal less than 0.1% of availability of pesticide active ingredient because of unavoidably reaching the loss that natural causes such as wind, temperature cause agricultural chemicals drift, evaporation, decomposition or degraded etc. in use to cause.Therefore,, particularly in order to prevent and treat resistant insect, have to use more heavy dose of and insecticide pesticide higher concentration, and increase spraying times, so formed vicious circle for improving insecticidal effect.Its result, cause the pesticide resistance population exponentially ground of insect to increase on the one hand, so that uncontrollable at all insect pest, on the other hand, caused pollution again to ecotopes such as atmosphere, waters and soil and agricultural product, directly threatening the people's of the whole society healthy, the safety of other relevant aquaculture and the living or death of wildlife resources, influencing and destroyed balance of nature.
In the face of this situation, all solve actively seeking effective measures hardy countries in the world at present.That is for example developing has biopesticide, low-toxin farm chemicals, a pesticide synergistic agent etc.But for various reasons, still fail at present to be widely used.For example owing to it kill reasons such as scope single-minded and preventive effect not good, make slow progress at present by application for biopesticide.Though low-toxin farm chemicals at present development is swift and violent, the screening exploitation is expensive big, and the cycle is long, and the same existence in the back of the coming into operation problem that can develop immunity to drugs, and along with the consumption increasing, can produce vicious circle again, has also just lost the practical significance of low toxicity.Pesticide synergistic agent also is a series products of developing energetically at present both at home and abroad, all is by the inhibitory action to the metabolic enzyme system in the harmful organisms usually, reduce pesticide active ingredient in vivo degraded and reach the purpose that increases preventive effect.But at present because at aspects such as manufacture difficulty, cost and photostability thereof, its popularization and use still have tangible limitation.Still control today of the main effective measures of agricultural pest at chemical pesticide, the pollution and the resistance that solve insecticide pesticide are current main research topics.
Except that insecticide, other is as the present effect downward trend that equally also exists in various degree of agricultural drugs such as weed killer herbicide, plant growth regulator, be to keep and improve result of use, also have the problem that strengthens aspects such as the environment that brought, economy, society because of consumption gradually.
The present invention's purpose at first is at the problems referred to above, the pesticide resistance that can significantly overcome pest is provided, thereby both can reduce the consumption of present multiple insecticide pesticide greatly, can significantly improve the agricultural chemicals synergist of control efficiency again, at the good effect that has comparatively desirable and development prospect aspect pollution that solves present insecticide and the resistance two.Further aim of the present invention provides except that can be used for insecticide, can also be widely used in multiple agricultural drugs such as agriculture sterilization, weeding and crop growth regulator, can obtain equally and reduce consumption, improve the agricultural chemicals synergist of result of use, make it have applicability and more vast potential for future development widely.
According to present above-mentioned present situation, researcher of the present invention is from another angle, promptly, not directly to control agricultural chemicals degradation in vivo in enzyme inhibitor mode in the organism, but, reduce evaporation discharge and increase seepage velocity and infiltration capacity by strengthening wetting action, improve the dose enter target, strengthen the result of use of agricultural chemicals in the mode of the actual effective rate of utilization that improves agricultural chemicals.And therefore make agricultural chemicals synergist of the present invention not only be confined to the insecticide class, and can be widely used in many-sides such as desinsection, sterilization, weeding and plant growth regulating.
Agricultural chemicals synergist of the present invention is by the Tweens surfactant, and the N-R-2-pyrrolidone-2 compounds reaches agricultural chemicals common solvent composition in case of necessity.Wherein the substituent R in the pyrrolidone-2 compounds can for H be or the C1-12 alkyl in a kind of.The volume content percentage of each component is:
Tweens surfactant 10～98
N-R-2-pyrrolidone-2 compounds 2～90
Agricultural chemicals common solvent 0～50.
Normally used multiple solvent in the present all kinds of agricultural chemicals, as methyl alcohol, ethanol, toluene, dimethylbenzene, acetone, N, little molecular solvent such as dinethylformamide or N,N-dimethylacetamide, where necessary, also can in agricultural chemicals synergist of the present invention, select to use.Certainly, as think and there is no need, also can not use.
Tweens surfactant in the above-mentioned composition, can be in Tween-20, Tween-40, Tween-60, Tween-65, Tween-80 or the Tween-85 at present commonly used at least a.Result of the test shows that in these Tweens surfactants, the principal element that is not to influence result of use is generally said in the change of kind or combination, and then the correlation with effect is bigger for what of its usage amount.Equally, N-R-2-pyrrolidone-2 compounds in the composition, substituent R can be selected in H and C1-12 alkyl, as, 2-Pyrrolidone, N-N-methyl-2-2-pyrrolidone N-, N-ethyl-2-pyrrolidone, N-octyl group-2-Pyrrolidone, N-dodecyl-2-Pyrrolidone etc. all can use.Result of the test shows that also in above-mentioned various pyrrolidone-2 compounds, the change of substituent R neither influence the principal element of result of use, and the consumption of pyrrolidones then has comparatively remarkable influence to result of use.These situations can be known in following result of the test and find out.
Experiment test result by Pesticides Testing mechanism shows, after agricultural chemicals synergist of the present invention and insecticide are used, can accelerate the speed that medicine penetrates into polypide greatly, comparative trial shows, the general permeating speed of agricultural chemicals that adds behind the builder of the present invention is 15～30 seconds, the equal infiltration that does not add the builder agricultural chemicals generally needs 15 minutes, and speed differs 30～60 times.
Indoor activity test according to Agricultural University Of Southwest shows, adds above-mentioned builder of the present invention and can make the virulence of decis control cotton bollworm increase more than 1 times; Make the virulence of flolimat control cotton aphid increase nearly 1 times; Make the virulence of the desinsection list control snout moth's larva of rice increase more than 2 times; Making goes out sweeps the virulence increase of sharp control mite class more than 9 times; Make the virulence of hexythiazox and flolimat complex preparation control two spotted spider mite increase more than 14 times.Do in the large tracts of land agricultural experiment in some provinces, farming reaches, Gramoxone adds with an amount of builder of the present invention after the amount of reducing by half respectively and is used to kill various weeds, general with use the preventive effect of former medicine full dose suitable separately.In the small size agricultural experiment, to decis, come good fortune spirit, time, go out sweep that profit, speed are slaughtered, hexythiazox, 1605, flolimat, isocarbophos, phoxim, desinsection list, dimehypo, cover grass energy, tribenuron-methyl, topsin, carbendazim and some other insecticide, miticide, bactericide, weed killer herbicide reduce by half in conventional amount used, and to add builder of the present invention an amount of in the back, the result all basic with use the preventive effect of the corresponding agricultural chemicals of full dose suitable separately.
