Comparative Study of Pesticide Resistant Soil Microbes from Mango Farms of Pallam and Nenmeni Panchayath in Muthalamada, Palakkad

Abstract

Abstract: In the current study a comparison between the soil bacterial population of Mango farm polluted and non-polluted with pesticide were carried out. The study showed that different insecticides were used in each growing season and that farmers apply a lot of pesticides to control pests of mango. Pesticides are applied once every three or four days. The mixtures for insecticides and fungicides used and at least three types of variations with doses of 30–40 ml for each type. Excessive use of pesticides has been known to be hazardous to the environment, affect soil fertility as well may impart toxicity in living beings including beneficial bacteria. Major bacterial genera found in the soil includes; Bacillus, Pseudomonas, Micrococcus, Serratia Proteus, Enterobacter. Bacterial resistance towards the pesticides used in the mango farms were studied using pesticides Hamla, Larincare and Zipvin in various concentrations like (2 μl/ml) (4 μl/ml) (6 μl/ml).It has been found that all the four bacteria can grow in the presence of pesticides indicating all the four bacteria is resistant to all the tested pesticides.
