Fumigants are volatile liquids. Their high vapour pressure distribute the gas through soils pores in all direction.The most economical and efficient fumigant for all type of soil was identified to the methyl bromide with the following advantage.
Methyl bromide controls all the soil borne pests like nematodes, soil borne fungi, soil borne bacteria, parasitic plants and soil insects. It also controls most of the annual and perennial weeds and liberates organic compounds, including N2 that temporarily increases soil fertility. A high concentration for a short time is as effective as a lower concentration for a longer time. |
