ROLE OF SOIL TYPE, PH AND TEMPERATURE ON THE EFFICACY OF NEMATICIDES FENAMIPHOS AND OXAMYL AGAINST Meloidgyne javanica
Under laboratory conditions, M. javanica in calcareous sandy loam soil was more sensitive to both fenamiphos and oxamyl. While it on clay loam soil was more tolerant to both nematicides. At LC50 level, the nematodes in calcareous sandy loam soil were the most sensitive to fenamiphos (LC50 : 0.72 ppm ) followed by those in sandy soil (LC50: 3.81 ppm ) and then nematodes of loamy soil (LC50: 5.03 ). The most tolerant nematodes were those in clay loamy soil (LC50 : 6.83 ). The same trend was found with oxamyl. The LC50 was arranged as follows : calcareous sandy loam, sandy, loamy and clay loamy soil 5.14, 9.27, 11.88 and 16.40 ppm respectively. Fenamiphos was more effective in the acidic media, specially in pH 5 while oxamyl was more effective in alkaline direction specially in pH 9. Under the temperature degrees of 30, 25, 20, 15 and 10 0C the LC50 of fenamiphos were 0.4, 0.8, 1.5, 4.7 and 4.8 ppm respectively. The same trend was found by oxamyl which gave the follows LC50 under the above mentioned degrees, 2.0, 2.7, 9.8, 20.8 and 27.9 ppm respectively. Generally fenamiphos was more effective than oxamyl.
