Description The study entitled “Pesticide Residues and Nutritional Quality of Selected
Fruits in Central Telangana Zone of Andhra Pradesh” was conducted to estimate the
pesticide residues in mango, sapota, guava, banana and papaya in fresh form and after
washing and the nutrient composition in fresh fruits. The other objective was to
determine whether the pesticide residue levels, if any, of the selected fruits before and
after washing were within the Maximum Residue Levels (MRLs). Comparison was
made between recommended package of practices versus farmers’ practices in the usage
of pesticides and nutrient composition against reference values.
Ten farmers each of mango, sapota, and guava while seven banana and five
papaya farmers were selected using purposive random sampling. The total forty two
farmers were interviewed using the structured questionnaire that was prepared for the
purpose. The questionnaire included information on the package of practices in relation
to pesticide usage for different fruit crops, dosage/hectare, mode of application, sources
for the procurement of seeds and pesticides, processing techniques which includes
washing fruits before consumption and affect of pesticides on health. The pesticide
dosage values hence found were compared against the recommendations specified by
the Package of Practices of the Important Horticultural Crops of Andhra Pradesh (2010)
recommended by Andhra Pradesh Horticultural University, in order to check whether
the interviewed farmers adhered to the recommendations or if any deviations existed.Burning eyes, nausea and headache were the most common immediate
symptoms experienced and most of them used masks, or gloves, very few used both.
Nearly twenty four percent did not use any precautionary measure while pesticide
application. The reasons for application of pesticides were quoted as higher yield, better
quality produce and prevention of pests. The farmers were aware of the use of natural
pesticides like neem oil and crude garlic oil instead of chemicals but are not practicing.
Most of them did not feel the need for washing the fruits before consumption as they
were unaware of the serious health effects of pesticides.
The nutrient compositions of selected fresh fruits were comparable with the
reference compositions with slight variations in moisture, reducing and total sugars.
Whereas, β-carotene levels of mango and papaya samples were almost 26% and 90%
less than the reference composition, while vitamin C content of guava sample was 52%
less than the reference composition. Such variations could be attributed to varietal
differences, soil conditions, seasonal variations, time of maturity and degree of ripeness.
Pesticide residue levels in all the selected fruits before and after washing were
below detectable limits (BDL). Pesticide residues in fruits were influenced by the time
lag between pesticide spray and fruit harvesting, storage, transport, handling and
processing techniques like washing and peeling before consumption of fruit. The lower
dosages of pesticides applied by the farmers than recommended could have also
contributed to the non-detectable levels of pesticide residues in the fruits samples.
Thus, the results of the present study indicate that the pesticide residue levels in
the selected fruits mango, sapota, guava, banana and papaya of Central Telangana Zone
are within the MRL levels and are therefore safe for human consumption. Preprocessing
techniques like washing with water or 3% salt water and peeling for
obtaining edible portion further reduced the residual burden as the residues fell below
detectable levels.
