However, most pesticides have active ingredients that are difficult to effectively diffuse, penetrate and coat onto the plant crop to be protected.
The synergist is a substance which has no activity, but can obviously improve the wetting, spreading, dispersing, retaining and permeability properties of the pesticide when being mixed with the corresponding pesticide. A plurality of pesticides need to be diluted before use, and a certain pesticide synergist is added, so that the dilution of the pesticides can be realized, and the pesticide effect of the pesticides can be improved. The synergist is very important to the using effect of the pesticide, and directly influences the efficacy of the pesticide.
Most of the existing pesticide synergists are oily preparations, are difficult to disperse uniformly in water and have poor penetration effect; moreover, the wetting and spreading performance on the plant leaf surfaces is poor, which is not favorable for the medicine to be quickly absorbed by the plants. In order to improve the surface tension of the pesticide and improve the wetting and spreading performance of the pesticide, the prior agricultural synergist is added with organosilicon, which is a polysiloxane surfactant and can reduce the surface tension and improve the wetting and spreading performance, but the organosilicon is unstable to acid and alkali, can be decomposed when the moisture is high, and is expensive. Therefore, it is necessary to research a synergist having good wettability and permeability.

As can be seen from Table 3, the control effect of the permeation enhancer prepared by the invention on cucumber powdery mildew reaches 97.8% after being compounded with a bactericide, which is much higher than that of the experiments 2 and 3. Therefore, the penetration synergist prepared by the invention can be compounded with the bactericide, and the control effect of the bactericide on target diseases can be obviously improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
