Organic silicon has no special effect on acidic pesticides in general, and does not have the effect of enhancing the efficacy, but it will reduce the effect of some basic pesticides (such as Bordeaux). Can produce phytotoxicity.

The editor of the pesticide network below highlights the dangers of agricultural silicones.

The hazards of agricultural silicones

I. Phytotoxicity (phytotoxicity)

Since agricultural organosilicon synergists will enter the medium and come into close contact with tissues, stomata penetration is one aspect of phytotoxicity; organosilicon synergists are mild to plants and generally beneficial. The key is the phytotoxicity of spray formulations. Therefore, in order to give full play to the effectiveness of silicone synergists, pesticide formulations must be optimized.

II. Harm

Generally speaking, silicone synergists are not more harmful than most pesticides; due to the extremely low surface tension of silicones, eyes should be protected when using silicone surfactants; because agricultural silicone synergists may penetrate Protective clothing is more toxic in this respect than conventional surfactants.

III. Environment

Based on the research on various pesticides, silicone surfactants are not different from other additives in this respect.


Organic silicone surfactants represent a new class of high-efficiency pesticide auxiliaries with a very broad application prospect far beyond the areas currently being explored. (Le Ling)
