Field experiments were carried out at Qaha farm, Qalyubia Governorate, Horticulture Research Institute, Agric. Res. cent., Egypt., to study the effect of 6 anti-stressor compounds on pepper under heat stress and insect infestation. Five anti-stresses classified as good desirable sources yield polyphenol oxidase activity (PPO) enzyme activities in leaves. Three these 5 anti-stress showed an increase peroxidase (POD) along with a high reduction whitefly Two three, namely aluminum silicate (AS) potassium (PS) exhibited significant positive effects for Thrips Spider mite infestations superiority early total well fruit quality, indicating possibility combining both quality characters various environmental conditions. Both combined three or more key studied characters, including vegetative growth, fruits terms flavonoid, TSS, pH, vitamin C, Total soluble protein. Additionally, AS had strong favorable versus PS all traits, most attributes, mean infestation reduction. Results suggest that mentioned treatments may be crucial maintaining yields and/or some essential elements traditional agricultural practices.
