| Abstract | ||
| The present study was conducted out to investigate the effect of foliar application of five pea cultivars (Entesar 1, Goara, Line 1, Line 11 and Line 14) with salicylic acid (SA) on infestation by Aphis craccivora (Koch.), Thrips tabaci Lindeman and Liriomyza trifolii Burg. during 2018/2019 and 2019/2020 winter seasons at Sohag Governorate. Also, the effect of SA application on the growth, yield, and some yield components of pea was included. Data revealed that the foliar application with SA at 200ppm and 100ppm reduced A. craccivora, T. tabaci, and L. trifolii (mines) infestations by about 50% and 30%, respectively, compared with control in both seasons. Also, plant height, the number of pods/ plant, weight, total green pods yield/ plant, and total yield/ Feddan were increased by the two SA treatments comparing to control in both seasons. The five pea cultivars varied significantly in their susceptibility to the three studied pests and in horticultural characters in both seasons. The interaction between pea varieties and SA treatments was discussed. | ||
