Abstract

The study of the effectiveness of several active ingredients of chemical insecticides in controlling insects in sweet potato plants (Ipomoea batatas L.) was carried out at the UMT Bukit Kor Agricultural Complex, Marang Trengganu Malaysia from 14 September to 21, 2023—research methods. The design used a randomised group design (RAL) with three treatments and three repeats, namely T0 Control, T1 Sulfoxaflor 1.5 gr/ 2 litres of water, T2 Buprozen + Cartap Hydrochloride 2 g / 2 litres of water. The observation of mortality percentage was carried out until the seventh day, and the result was calculated using the formula M a/b x 100 %. The Brine Shrimp Lethality Test (BSLT) is used to observe compounds' toxicity. The result obtained is calculated as the LC50 (lethal concentration) value. The results showed that the toxicity of both insecticide active ingredients used was considered very effective for controlling target insects of the Hemiptera order. The active ingredient Sulfoxaflor obtained an insect mortality percentage of the order Hemiptera by 100%, and the active ingredients Buprozen and Cartap Hydrochloride obtained 100%. However, non-target organisms such as the Araneae order, a natural enemy, namely Oxyopes javanus, are also affected by 100% toxicity of the two active ingredients, from calculating the LC50 value from probit analysis after obtaining results. The LC50 value obtained is 47.11 ppm. The LC50 value of these two insecticides has a toxic potential because the value is below 1000 ppm.
