This paper discloses the fact that heavy and unscientific dosages of chemical
pesticides and application practices seriously affect the ecological and
environmental balance. Thus, this paper attempts to highlight some important
issues associated with cotton cropping in Guntur district like land preparation,
seed treatment, intercropping, crop rotation and avoidance of contiguous cotton
fields. This study also analyses the pest management practices at different
stages of crop growth and points out certain interesting findings about the
cotton growers. Firstly, they are not fully aware of the importance of pre-sowing
pest management practices. Secondly, the cotton farmers are not accustomed
to using the labeled seeds. Thirdly, the farmers are not fully familiar with the
use of different control methods, though most of them are in a position to
correctly identify the various pests, insects and diseases attacking the crop.
This can be attributed to the excessive dependence of the farmers on the
dealers, company agents and their fellow farmers for identification as well as
adoption of control measures without resorting to the agricultural extension
personnel adopting the chemical method. This study concludes that there is a
need to educate the farmers about the pest management practices through
training and timely demonstration.
Use of chemical pesticides and insecticides are the main component of pest and disease
management practices. But heavy and unscientific dosages of chemical pesticides and
application practices seriously affect the ecological and environmental balance. Pesticide
usage also causes irreparable damage to human beings, either directly or indirectly. Seepage
of heavy pesticide residues into water and soil makes the water polluted and soil diseased.
Pollution makes the water un-potable, lowers fish production and contaminates the food. The
effluents discharged by the pesticide manufacturing plants also get into the ‘food chain’.
In the Indian context, food commodities, for these reasons, right from wheat and rice to
milk and milk products, are found to contain high levels of pesticide residues of DDT, BHC,
Diledrin and Malathion. On an average, an Indian’s body has the highest DDT levels rangingfrom 12.8 to 3.1 PPM. Further, WHO has graded most of the pesticides used by Indian farmers
as hazardous (Ravi and Thimmaiah 1995:51). It was also established that, usage of hazardous
pesticides leads to asthma and skin disorders, enlargement of liver, psychological problems
and to some extent, even degeneration of nerves, often resulting in paralysis. It was further
reported that pesticide poisoning is causing large casualties (Parvinder 1997:50). |
