Abstract

The effect of the Antifeedant tolfenpyrad in the proportion of activation, synergy, and potentiation of pesticides oxaymatherin, acetamiprid, and lufenuron against Colorado beetle larvae and adults were studied. The results showed Exultance effect on Toxicity. The results also showed Exultance mixing Acetamiprid with antifeedant Tolfenopyrad pesticide toxicity to the activation of the pesticide in the larvae the third instar at a rate of 1.72, where was the rate of potentian reach 1.7.   The antifeedant Tolfenopyrad mixture with insecticides Lufenuron and Oxymathrin each alone had antagonism effect where the activation rate reached 0.17 and 0.54 respectively. While the activation effect of mixing antifeedant Tolfenpyrad with the insecticides oxaymatherin, acetamiprid, and lufenuron against adult of Colorado beetle had antagonism effect reached 0.124, 0.524, and 0.614, respectively.
