Studies of Insecticide Fenvalerate on Growth parameters and production of Gossypium hirsutum L.

Nitu Pathak


Cotton is the most important cash crop. Cotton constitutes more than 70% of the total world consumption of fibres. Cotton is reported to be a host for about 166 different species of insect pests throughout its growth cycle. The major pests of cotton are causing considerable economic losses to the crop production. The cotton farmers incur heavy losses on the crop due to these factors. Saubhagya variety of Gossypium hirsutum was selected to carry out the research work during the period of 2004-2007. Variety LRK 516 is used as a check variety with known characters. Cotton crop is highly susceptible to various insects’ pests. About 166 different species of insects’ pests are reported to attack cotton at various stages of its growth. Amongst these the cotton bollworm Helicoverpa armigera, the Whitefly Bemisia tabaci, Jassids, Aphids, Empoasca devastans and the pink bollworm (Pectinophora gossypiella) have been causing economic damage to cotton crop all over the country. However, by the end of the first 60-75 days, Fenvalerate treated cotton fields were looking as good as those which were unsprayed. This elicited a strong positive response. Fenvalerate is a synthetic compound primarily used as an insecticide. It acts as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants.

Keywords: fenvalerate sprays, Gossypium hirsutum, morphological characters and yield
