In a field experiment, twelve commercial agro-products were applied as soil
drench and 14 as foliar spray as recommended method of application and dose.
The results indicated that Biofertile product was the best which had the highest
suppressive effects followed by Algeferet and Perfect applied as a soil drench
compared to nematode check. The most effective one of products applied as a foliar
spray was Indole buteric acid then Feedchem and Amino strong with no significant
differences. The experiments indicated that the SAR commercial materials
(Nemakill, Indole-3 butyric acid, Gibirilic acid, Indole-acetic acid, Salicylic acid, Citric
acid and Glutamic acid) applied as foliar spray reduced nematode counts and
reproduction under all conditions. The Mega NPK recorded the best improvement in
plant fresh and dry weights and yield criteria. Our results concerning plant growth
and yield were highly significant in foliar application treatments more than soil
application and the compounds used to induce systemic acquired resistance
exhibited more enhancements in plant growth criteria and yield.
