| Abstract | ||
| Chemical pesticides have been used in agriculture and horticulture for several decades as a brute force method of achieving pest control. As a result, the persistence of some of these chemicals has left a long-lasting impact on the environment and non-target organisms. Pollution, pest resistance, and possible implications to cancer and diseases are a few such impacts. Modern pest control is shifting away from reliance on persistent chemical pesticides in favor of a more integrated approach to pest management. Applied biological pest control is an important component in an Integrated Pest Management (IPM) program. The main objective of the current research is reducing the organism damage due to these individual mechanisms in conventional agricultural spray application system by using the direct injection of bio-pesticide. The tequniche of biopesticied (Bacillus Thuringiensis . BT) was constructed and developed in Agriculture engineering dept. kafr El.sheikh University. The result indicate the mean values of B.T. spores for direct injection and Albuz B nozzle were 4×106, 6×107 and 8x107 at operating pressure 250 kPa, 150 kPa and 100 kPa respectively. Further more, the values of B.T. at the same operating pressure for indirect sprayer were 1×105, 4×105 and 8x105 at operating pressure 250 kPa, 150 kPa and 100 kPa respectively | ||
