Abstract
A field study was conducted to compare the efficiency of the Microbial insecticideButoxy bacillinein five concentrations: 0.09, 0.11, 0.13, 0.15 and 0.18%. These concentrations achieved the following biological activity against the American Cotton Bollworm 66.6, 84, 88.2, 92.8 and 96.8%, respectively. A field study was carried out to compare the active concentration for the BTB (0.18%A.I) with five insecticides from different chemical groups: Arrivo 50 ml/100 liter water, Danitol 15 ml/100 liter water, Methyl Parathion 150 ml/100 liter water, Lannate 50 g/100 liter water, Sevine 175 g/100 liter water. The results obtained showed a high efficiency for the four insecticides, in the following descending order: Arrivo 25% (0.012% A.I), Butoxy Bacilline 45% (0.18% A.I), Danitol 10% (0.0015% A.I), Methyl parathion 50% (0.075% A.I). These four insecticides achieved the following biological activity 96, 95.2, 94.4 and 92.4%, respectively. Whereas, the other two insecticides with lower biological efficiency were Lannate 90% (0.045% A.I) and Sevin 85% (0.14% A.I), with a mortality rate of 85 and 79.1%, respectively.
