| Abstract | ||||
| Greenhouse trial was conducted to assess the impact of three chemical nematicides i.e. Furdan, Gupter and Mocap in contrast with the oxamyl on vegetation of squash cv. Elxandrany under the stress of M. incognita contamination at the greenhouse situation (25± 3◦C). The obtained data indicated that all tested nematicides enhanced squash plant growth with various degrees. Mocap surpassed extra chemicals in the increment percentage increase values of plant length (83.65%), quantity of flowers and leaves (85.39& 56.54%) sum plant fresh weight (35.2%) and shoot arid weight (87.1%), and surpassed other chemicals in surpassing final nematode population (96.0%), number of galls and eggmasses (99.2 & 99.9%), followed by Gupter with values of 95.1, 98.6 and 99.1% for the similar nematode criteria, comparing to nematode only, in that order. Furdan exhibited the slighter values in this respect. The rate of nematode reproduction factor (RF) of M. incognita on squash were negatively affected by the tested nematicides and ranged between 0.077 for Furdan and 0.12 for oxamyl vs 1.97 for nematode single-handedly, respectively. The root galls and eggmasses indices of furdan and Gupter were on parity (3&3 and 1&1), respectively vs. 5&5 for nematode alone. Oxamyl as the typical nematicide gave indices of galls and eggmasses values of 2&2 vs 5&5 for nematode alone, respectively. | ||||
