Efficacy of soaking cotton seeds within salicylic acid and potassium silicate on reducing reniform nematode infection

The efficiency of soaking cotton cv. Giza 45 seeds in five concentrations of salicylic acid and potassium silicate (5, 10, 15, 20 and 25 mg L −1 against Rotylenchulus reniformis infection showed a significant (P < 0.05) improvement in the tested plant parameters that was distinct in soaked seeds...

Summary:The efficiency of soaking cotton cv. Giza 45 seeds in five concentrations of salicylic acid and potassium silicate (5, 10, 15, 20 and 25 mg L −1 against Rotylenchulus reniformis infection showed a significant (P < 0.05) improvement in the tested plant parameters that was distinct in soaked seeds in salicylic acid for 24 hours compared with potassium silicate in greenhouse (28 ± 5 °C). The application of concentration (20 mg L −1 ) stated the highest values of improvement of plant criteria, while high concentration (25 mg L −1 ) revealed the maximum reduction rates in the total nematode population for both potassium silicate and salicylic acid. Moreover, seed soaking in salicylic acid and potassium silicate achieved a considerable increment in nitrogen, phosphorus, potassium, phenol and chlorophyll contents in cotton leaves with changeable values.
