1, super expansion ability, more conducive to the drug liquid wetting target drugs
The expansion of the liquid on the surface of plant leaves or the surface of pests directly affects the efficacy, which is closely related to the surface tension of the liquid. After the liquid is applied to the target, the wetting effect can be achieved only when the surface tension of the liquid is below the critical surface tension of the target. The greater the surface tension, the less likely the liquid is to wet the target, and the less liquid is absorbed and permeated by the target, and the worse the effect of the drug. Take plants for example: The critical surface tension of plants is generally above 30 caine, the surface tension of clean water is generally 72.4 caine, and the surface tension of conventional drug active agent is the lowest about 30 caine. However, if the organic silicon surface active agent at the polar of surface tension is added to the liquid medicine, the surface tension of water can be reduced to about 21-22 caine. The leaves of wet crops or weeds that allow the liquid to flow more quickly allow the leaves to absorb the liquid earlier and more quickly, thus naturally greatly improving the effectiveness of the drug control. For example, the surface tension of the drug solution diluted by 0.5% methamabamectin benzoate 2000 times is 35.8 caine. If the organic silicon surfactant is added to the drug solution, the surface tension of the drug solution can be reduced to 22.2 caine, and the wetting effect of the drug solution will be significantly improved. In addition, because most of the surface of plant leaves and pest body surface skin stratum corneum, waxy layer, nap or rough surface is not easy adhesion solution, spraying with water to dilute liquid directly on the surface is not very stable, is neither easy adhesive wetting, also easy to tumble nature or slip because of the shaking force, will cause a loss of effective ingredients, It doesn't work as well as it should. The addition of silicone surfactants with super extended wetting ability can solve these problems and maximize the efficacy.
