Controlling Pest In Millet And Pulses
About the Practice
As informed by Karsanbhai, the pests damage the crops of pearl millet (Pennisetumtyphoides) and pulses on a very large scale, by eating away the leaves and flower. These pest breeds profusely, so if precautions are not taken, the entire crop is destroyed in 15 to 20 days. To control it, the fresh, green leaves with twigs of swallow wort (Calotropisprocera) are placed on the field 15 - 20 feet apart. After two days, it is observed that the insects pest descend down to feed upon the swallow wort leaves. At this time, the insects are picked and put into the earthen pots. When these pests are collected from all the fields in the above said manner, the pots are buried in deep pits dug outside the field boundary. According to the farmer, this is a very effective method of controlling the insect’s pest and it can repeated if the insects reappear. Source of the method was employed after learning that pests like to feed upon swallow wort and pigeon pea (Cajanuscajan) leaves.

"The residual film toxicity, fumigant toxicity and repellent effect of methanol extract of root bark of Calotropisgigantea (Linn) and its chloroform and petroleum ether (40- 60°C) soluble fractions were evaluated against several instar of larvae and adult of Triboliumcastaneum. In residual film toxicity, methanol extract and its chloroform and petroleum ether fractions showed insecticidal activity against T. castaneum and data were analysed by probit analysis."

"Scientists have developed farming techniques which bring socio-economic sustainability to crop production and protection (Machado, 2007). Integrated Weed Management (IWM) is one of those techniques whereby allelopathy can be used as an eco-friendly tool in weed management (Dangwal et al., 2010). Angiosperm plants have vigorous type of important toxic substances used for weed control (Han et al., 2008). Many of the crops are said to have toxic viability and a great deal of effort has been made to avail them for weed management (Travlos et al., 2007)."
