Maize stem borer (Chilo Partellus), poses a substantial threat to maize crops all over the world, causing damage that ranges from 26.7% to 80.4%. Its destructive impact includes killing the shoot in young plants, leading to a “dead heart,” and damaging the upper stem in older plants through boring activity. To combat this issue, a field experiment evaluated various insect growth regulators (IGRs) such as Lufenuron®, Pyriproxyfen®, Sitara®, Viper®, Track®, and Priority®. These IGRs, known as reduced-risk pesticides, target pest juveniles and are less harmful to beneficial insects. Conducted through a Randomized Complete Block Design (RCBD) with 24 treatments, excluding a control group, the study recorded maize stem borer populations at 3, 7, and 14 days post-IGR application. In conclusion, the study identifies pyriproxyfen® and Priority® at double the standard concentrations as highly effective insect growth regulators in mitigating maize stem borer infestations, offering promising avenues for enhanced pest control strategies in maize cultivation.
