This study was carried out at El-Ryiad region, Kafr El-Sheikh Governorate under field conditions during two okra growing seasons, 2018 and 2019 for examining the effect of some elicitors plant (Salicylic acid and jasmonic acid) only and mixture with conventional chemical insecticide compared with conventional chemical insecticide, actacron against the American bollworms , Helicoverpa armigera (Hübner), the spiny bollworm Earias insulana (Boisduval) ) (Lepidoptera: Noctuidae) and okra crop production.
The obtained results showed the potentiality of the highest concentration of jasmonic acid mixture with actacron for controlling both H.
armigera and E.
insulana as a new approach.
The grand reduction percentage of H.
armigera and E.
insulana were 97.75, 98.06 and 89.79, 87.54% respectively, in case of okra treated with at the highest concentration 300 ppm of jasmonic acid mixture with actacron (375 ml/ fed.) during at the two successive seasons 2018 and 2019.
However, the lowest redaction percentage of H.
armigera and E.
insulana were 59.26, 61.08 and 55.87, 54.15% respectively, in case of okra treated with at the lowest concentration 100 ppm of salicylic acid during at the two successive seasons 2018 and 2019.
Also, the highest concentration (300 ppm) of salicylic acid mixture with actacron (375 ml/ ffed.) showed moderately control to H.
armigera and E.
insulana, where the reduction percentages ranged from 78.34 -53.82 and 75.62-51.14 and for E.insulana the reduction percentages ranged between 73.27-48.39 and 71.64-46.67% at three examined rates during the two seasons 2018 and 2019, respectively) compared with other treatments.
The highest concentration of jasmonic acid (300 ppm) was more concentration of predators than other treatments.
The lowest of predators were found on okra plants in case treated with conventional insecticide.
The treatment with highest (300 ppm) of jasmonic acid mixture actacron showed the positive effectives in okra yield.
