The effects of pesticide spraying amounts per plant on insect pest control were investigated in a paprika cultivation. The paprika plant lengths of 1 m 20 cm and 2 m 20 cm were selected. In the case of 1m 20 cm high plants, 125 ℓ, 60 ℓ and 30 ℓ per 10 a were sprayed for individual application doses. When 125, 60 and 30 ℓ of pyrifluquinazon 10% WG were spra ed, control effects of 100%, 100% and 65.5% were shown 7 days later respectively. When the same quantities of clothianidin 8% SG were sprayed, control effects of 91.5%, 87.5% and 55.5% were obtained, respectively. The 2 m 20 cm high plants were sprayed with 250 ℓ, 125 ℓ and 60 ℓ per 10 a for individual application doses. When sprayed with pyrifluquinazon 10% WG, the plants showed control effects of 100%, 100%, and 58.5% 7 days later, respectively. When the clothianidin 8% SG was sprayed, control effects of 91.5%, 87.5%, and 55.5% were observed 7 days later, respectively. Frankliniella occidentalis control effects were tested using spinetoram 5% WG and abamectin 1.8% EC. In the case of 1 m 20 cm high paprika plants, when 125 ℓ, 60 ℓ, and 30 ℓ per 10 a of spinetoram 5% WG were sprayed, control effects of 93.1%, 90.1%, and 27.2% were shown 7 days later, respectively. In the case of abamectin 1.8% EC, control effects of 92.5%, 85.5%, and 56.5% were shown, respectively. When 2 m 20 cm high paprika plants were sprayed with 250 ℓ, 125 ℓ, and 60 ℓ per 10 a of spinetoram 5% WG, they showed control effects of 93.5%, 94.9%, and 67.5% 7 days later, respectively. In the case of Abamectin 1.8% EC, control effects of 90.5%, 87.5%, and 47.3% were shown, respectively.
