ABSTRACT:
This study was conducted to evaluate the effect of the following chemical pesticides ( Chmozinon 60 % Ec , Neuron 500 Ec , Ridomil Gold MZ 68,Sulfur, Vitavax WP)on the type of fungi predatory nematode ( Arthrobotrys oilgospora,Trichoderma harzianum, Paecilomyces lilacinus ) in culture media and soil
The results showed that A.oligospora were most tolerant to pesticides ,as it reached inhibition percentage 22.22% followed by T.harzianum31.55% and the P.lilacinus 45.11%, Compared to control treatment where the inhibition rate was 3.8%. The most effective of pesticides on fungi are (Neuron, Vitavax and Ridomil Gold MZ) Respectively ,while the pesticides(Sulfur, Chemozinon) have no significant effect on fungi ,but the Ridomil Gold MZ, has significant effect on P. lilacinus and T.harzianum only. |
