Biological Efficiency of Polyethylen Plastics and Idefix (Cupric Hydroxid 65. 60%) in Injection Against Tomatoes bacterial wilt (Ralstonia Solanacearum (Smith, 1896) Yabuuchi and al., 1996) and their Effects on Soil Microorganisms, in Burkina Faso

Abstract
– A study of biological efficiency of polyethylene plastics and bactericide idefix (cupric hydroxid 65.60%) in injection into the root system against tomatoes bacterial wilt and their effects on soil microorganisms, have been done, at Kou Valley, in Burkina Faso. This tomatoes disease causes big damages to farmers. The number of bacteria (R. solanacearum) has been evaluated on SMSA media. The levels of infection development have been evaluated using AFANASSEVA and al. (1983) formula. The quantification of soil microorganisms have been done by counting their colonies on the different media. The white polyethylen implementation reduced the level of bacteria (R. solanacearum) from 34. 50% to 50. 00% in comparison with untreated control. The efficiency coefficients of polyethylen plastics varied from 0. 00 to 97. 93 and those of injection method from 0. 00 to 43. 45. At the complete maturation, the number of cellulolytic bacteria, microscopic fungies and ammonifying bacteria, was higher than the one of the tomatoes raising period. The polyethylen plastics have allowed two fold increase of yield in comparison with the untreated control. The injection method gave a yield increase of 87% in comparison with the untreated control. The use of black or white polyethylen plastics, as presented, gives prospect of a new integrated pest management method against tomatoes bacterial wilt without side effects on human health and environment.
