About the Practice

Ratilal takes 200 g of Morthuthu or CuSO4, limbunaful or citric acid, Hirakashi or FeSO4 and tobacco (Nicotiana tabacum) which is used in a big container of hukka and adds five litres of water to it. This mixture is kept undisturbed for 10 days. It is stirred well and filtered through a cotton cloth. Approximately 70-80 ml of the filtrate is added in 10 l of fresh water and sprinkled on the crop for any larval pest. According to Kachhadiya about 70% success is achieved in controlling the larval pest in cotton. Many farmers from his village have also started making use of this practice.

PAS 1:

"Dengue is an infectious disease transmitted by the bite of female Aedesaegypti during blood feeding, for continuity of the reproduction process. Population mosquito control has been carried out for decades, through the intensive use of conventional insecticides. The Bordeaux Mixture (BM) is a colloidal substance with insecticidal activity, bactericidal, fungicidal and molluscicide and can act comprehensively to control immature forms of A. aegypti, in addition to altering the physical and chemical conditions in the breeding and food chain insect. The values for the lethal concentrations of BM were CL10 1.05 mg L-1 (confidence interval 0.70 - 1.34), LC50 3.06 mg L-1 (2.73 - 3.35) and LC90 8.94 mg L-1 (7.42 - 11.92). The results of this study allow us to propose the BM as insecticidal potential for population control insect vectors."

PAS 2:

"Larval mortality rates recorded were in the following
sequences: orthophosphoric acid and lactic acid at 1:1 combination >orthophosphoric acid>lactic acid."

PAS 3:

"In glacial acetic acid 100% mortalities of third instars larvae of Cx. quinquefasciatus were recorded at 0.5% concentration after 72 h of exposure. Cx.vishuni group showed 93.33% mortality at 0.5% concentration after 72 h of exposures and An. stephensi larvae showed 83.33% mortality at 0.5% concentration after 72 h of exposures (Table 1). Rate of mortality (Y) was positively correlated with the concentration (X) of the organic acid and the regression coefficient values were nearer to 1 (Table 2). No mortality, abnormal behavior and sluggishness were found in non-target organisms."[Adhikari, Utpal& Ghosh, Papiya& Chandra, Goutam. (2012).
