In modern agricultural production, the use of pesticides has become a crucial means of ensuring crop health and increasing yields. As an indispensable agent in agricultural production, pesticides have played a significant role in promoting the development of agriculture in my country. However, with the widespread application of pesticides, a problem that cannot be ignored has gradually emerged – the generation of foam during the preparation and spraying of pesticides often leads to reduced efficacy and even environmental pollution, negatively impacting crop growth. To address this problem, pesticide defoamers have emerged, becoming a key additive in ensuring the effectiveness of pesticides and promoting sustainable agricultural development.
What factors cause foaming in pesticides? Let's look at the factors that may cause pesticides to foam. First, there is the influence of surface-active substances. Different types of pesticides contain different chemical components, some of which are surface-active and easily form foam in liquids. For example, pesticides containing surfactants such as organosilicon and polyethers are more prone to foaming. The higher the concentration of the pesticide, the greater the likelihood of foam formation. This is because high-concentration pesticides have a higher content of surfactants, making it easier to form foam in the liquid. In addition, foam is also affected by other physical factors. For example, during the use of pesticides, stirring and vibration cause the air in the liquid to come into full contact with the pesticide, thus promoting foam formation. Furthermore, strong stirring and vibration can also lead to the rupture and regeneration of foam, making the foam more stable.
What are the potential harms if pesticide foaming is not controlled or eliminated? Foam can reduce the efficacy of pesticides, affecting their coverage and adhesion capabilities, preventing the liquid from uniformly adhering to crops or pests, thus reducing the effectiveness of the pesticide. It can also increase the difficulty of pesticide spraying operations, affecting the normal operation of spraying equipment, such as clogging nozzles, resulting in uneven spraying, and even causing equipment damage, increasing maintenance costs and operational difficulties.
Pesticide defoamers are compounded from specially modified polyethers and fluorine-containing raw materials through a special process. They are easily soluble in water and are particularly suitable for use under conditions of high temperature, strong acid and alkali, high shear force, and high pressure. They continuously maintain defoaming and anti-foaming properties in agricultural product series. It possesses excellent high-temperature resistance, acid and alkali resistance, does not float or separate from oil, and can be used to eliminate foam in various harsh systems over a wide temperature range.
