of NNI-0101 treated insects

NNI-0101 shows two distinct effects on aphids; 1. Rapid response of abnormal behavior (insect dispersion, feeding cessation)2. Slow lethal action

Possible IR-4 InterestsOnion thrips (PCR submitted)Aphid, Thrip, Whitefly, Mealybug and Scale control on ornamentals

Rapid cessation of whitefly and aphid feeding reduces transmission of viruses vectored by these pests on important fruit and vegetable crops
