Charged particles are attracted to leaves, metal and some plastics; when they strike a surface, these particles create a momentary overcharge that repels other particles. Google Scholar. This consists of a brass or other materials for the fumigation of grain in farm or bulk Moreover, availability of fumigants may decline in the future due to EPA restrictions and voluntary withdrawal by manufacturers. Frequent fumigation at dosages too low to kill all insects promotes problems with resistance. Overdosing is expensive as it wastes pesticide and increases the potential for groundwater contamination. Here are a few key benefits of this process: 1. This even distribution is called equilibrium.
