About the Practice

One should be careful before storing the grains in the granary. Due to the stored pest, the keeping quality of grain deteriorates. The exiguous holes are observed on the grains by which the grains are not used for the food purpose. To prevent the infestation before storing the grains in the granary, use extract of worm killer (Aristolochia bracteata) and wind killer (Clerodendrum phlomidis), which is sprinkled on the empty container before placing the grains in the container. The 250 ml extract is sprinkled on 800 kg of grains. The grains are protected one year from the infestation.

Practice Details

Formulation: Extract of worm killer (Aristolochia bracteata) and wind killer (Clerodendrum phlomidis)
Ingredients: Extract of worm killer (Aristolochia bracteata), Extract of wind killer (Clerodendrum phlomidis)

PAS 1:

"Antifeedant and larvicidal activities of hexane, chloroform and ethyl acetate extracts of Clerodendrumphlomidis and Flueggealeucopyrus at 5, 2.5, 1.0 and 0.5% were studied against III instar larvae of Eariasvittella. Hexane extract of F. leucopyrus and chloroform extract of C. phlomidis showed maximum antifeedant activity of 81.00 and 80.48%, respectively at 5% concentration. The least LC50 and LC90 values of 1.21 and 1.36% for hexane extract of F. leucopyrus and 4.96 and 5.11% for chloroform extract of C. phlomidis, respectively. Cent percent larvicidal activity was observed in chloroform extract of C. phlomidis at 5% concentration, while hexane extract of F. leucopyrus recorded at 87.52 and 5% concentration. The LC50 and LC90 values for larvicidal activity ware 0.51 and 1.74% for chloroform extract of C. phlomidis and 1.74 and 4.69% for hexane extract of F. leucopyrus, respectively. No adult emergence was observed at all concentrations of C. phlomidis chloroform extract and at 5 and 2.5% concentrations of F. leucopyrus hexane extract." [C. Muthu, K. Baskar, S. Kingsley and S.

PAS 2:

"TheIso-propyl alcohol extracts of both Clerodendrumpholmids and Scopariadulcis showed best result of larvicidal and pesticidal activity against the mosquito larvae Aedesaegypti, and the pests Sitophilusoryzae (Rice weevil). In the present investigation the n-butyl alcohol extacts of Clerodendrumphlomidis showed very good activity against all tested pathogens."

PAS 3:

"Repellent effects of the highest concentrations of scorpion root extracts on the 3 rd instar larvae ofT. granarium. All the tested treatments reflected highly significant repellent effects, ranged between 61.7% and 89.5%repellency, as compared with the control. The highest repellency percentages were achieved by the fruits methanol extractand leaves ethyl acetate extract (89.5%), however all fruits extracts were non significantly different from the latter twotreatments. Regarding roots organic extracts, methanol extract revealed the best significant repellent effect."
