PROBLEMS AND SOLUTIONS OF PESTICIDE MISMANAGEMENT




With the recent crash in global oil price, which has resulted to economic meltdown, most countries especially African countries that were depending on crude oil export are returning back to agricultural based economy and with the encouragements and supports from various governments, a lot of  people are moving into this sector and this  has subsequently and rapidly raise  the application of pesticide  to control the incidences of pests and disease outbreaks.
              Though application of the pesticide controls the pest problems to some extent in the long term it brings lots of problems like pest resistance, minor pest outbreak and soil, water contamination. Increasing the use of pesticide in the field crop is not the ultimate solution, as it comes with  its own negative effects hence the need to create farmers awareness  about specific pesticide use, their safe handling and disposal procedure, direction of use etc
             Most of the farmers take pesticide as medicine that is used to cure crops from diseases and pests. But actually it is the toxic materials that either kill or deteriorate the growth of the pests increasing the yield of crops.
 Some of the pesticides have comparatively high residual effect which consequently creates health hazards due to the accumulation of the pesticide residue in different tropic levels of the eco-system. They persist for a long time in the environment and cause environment problems.
          Most farmers  lack the knowledge   about the proper use of the pesticide and at the same time would not like to  employ a professional pest controller rather they would prefer ‘ do it yourself’ system. This is not good. In addition to this,, some of the  pesticide resellers or shopkeepers and distributors  do not  have enough knowledge on safe use of pesticides and storage management, they also lack knowledge on specific pesticide that are made for specific pest and disease, effective direction of usage ,proper handling and storage of pesticide ,proper transportation and sound disposal methods and cannot offer good advice on them to the farmers since most of them are bought over the canter.

IMPLICATIONS OF PESTICIDE MISMANAGEMENT




               A research has shown that “Fetuses, infants, growing children, pregnant and nursing mothers, and women of childbearing age are most at risk from adverse health outcomes from exposure to pesticides.  Children are more at risk than adults because children eat more relative to their body weight than adults eat.” Our farmers and consumers need to know good agriculture practices (GAP) and the government should focus to strengthen its extension services to the community level.There have been  a lot of cases of people being hospitalised after consuming agricultural products.

SOLUTIONS 
Use of the indigenous knowledge and practices like using ash, neem powder, etc as practice in some countries like Nepal  must be promoted with possible scientific manipulation to strengthen the efficacy of indigenous practices. Use of bio-pesticide and other environmental friendly means are alternatives. For example, washing vegetables with water for one minute at room temperature results in approximately 40 to 90% reduction of the levels of the pesticides originally detected on the produce.
            Similarly, washing of the vegetables and fruits three times reduces the residue by 60-70% and dipping of agricultural produce in vinegar or salt for 15 minutes before cooking followed by thorough washing can reduce the residue by 70-80%. These types of practices must be communicated to the entire consumers via the social media. Also per boiling of  agricultural products  like rice and beans etc and thorough washing  is also advisable
Farmers should engage the service of a professional pest controller rather than do it yourself style.

              During fumigation, direct liquid spray of chemicals on agricultural products like rice, beans  maize etc should be avoided
Killing and consuming  of wild animals(bush meat as known in some countries) with chemically induced bait should be seriously discouraged
