insects will gradually develop resistance to the pesticide however during this period soils ecosystem will be badly hurt . Soil's ecosystem has insects in the main role. While soil quality will degrade it's water absorption rate will also drop and will have high concentration of salts which will eventually give acidic properties to soil. Growth of plants , crop will entirely depend on fertilizers and not on soil's natural properties ( constituents of soil).
