About the Practice

Arjanbhai D Kodarv of Banaskantha district in Gujarat controls the pests Spotted bollworm and Pink bollworm in cotton by spraying a solution made of mahua or butter tree (Madhuca indica) and tamarind (Tamarindus indica) bark. In order to control the infestation Kodarv makes a 500 ml stock solution with equal amounts of mahua or butter tree (Madhuca indica) and tamarind (Tamarindus indica) bark. The solution is filled in a 15 L capacity pump and sprayed on the infected crop. If the attack is severe then the solution is sprayed once again after a week. But this solution needs to be used judiciously because if used more than twice then there are chances of the roots of the plant getting burnt. Kodarv has been using this practice for over 30 years. Make a 500 millilitres stock solution with equal amounts of mahua or butter tree (Madhucaindica) and tamarind (Tamarindus

PAS 1:

"The four medicinal plants reduced the mean leaf area consumed by 7day old larvae in the order M.indica (4.88cm2 )>B.orellana (6.07cm2 )>A.chinensis (10.06cm2 )>C.procera (15.34cm2 ). B.orellana was most toxic showing 96.66% terminal larval mortality. M.indica leaves showed a visible effect on the ecdysis and development of insects. The insects fed on M.indica leaves were not able to moult into the next instar and finally died. M.indica and B.orellana were most toxic as natural botanical control agents in limiting the insect population. C.procera and A.chinensis were also detrimental to S.litura 7 day old larvae showing 56.66 and 70% adult emergence. All the medicinal plants were effective in controlling the growth and development of S.litura.

PAS 2:

"The insecticidal activity of n-hexane, methanol and water extracts of Tamarindusindica, Azadirachtaindica, Cucumissativus, Eucalyptus species, Switeniamahagoni, and Psidiumguajava leaves were investigated by using the Film residue method against a red flour beetle TriboliumcastaneumHerbst. The results showed that four plant extracts showed a strong to moderate toxicity at a different concentration on red flour beetle. Among them, Cucumussativus leaves extract showed highest mortality (80%) whereas Psidiumguajava extract showed lowest mortality (50%). Among the solvents, the hexane extracts showed more toxic effect than other extracts. The LC50 results revealed that the hexane extract of Cucumussativus is the most toxic to the pest followed by the hexane extracts of Azadirachtaindica and Tamarindusindica. Qualitative phytochemical analysis has also been performed. [Mostafa, Dr & Hossain, Hemayet& Hossain, Md. Anwar & Biswas, Pizush&Haque, M.. (2012).

PAS 3:

"The finding of the present investigation revealed that methanol extract (T. gallica) possesses remarkable larvicidal and adulticidal activity against C. capitata, the most important agricultural pest fly. Considering toxic effects of methanol extract of the plant, it is possible that the extract can be used as natural control agents. The plants is widely distributed and easy grown. Furthermore, the extraction method is simple and cost-effective and the application techniques could be relatively easily designed for on-farm use. Studies to confirm this hypothesis under field conditions and the non toxicity toward non target organisms are underway on our laboratory. Also, Further work to isolate and identify the insecticidal constituents of the crude methanol extract of T. gallica is needed.
