Performance of chafer and Japanese beetle products
View Larger
Dr. David Shetlar (Ohio State University) has summarized 28 years of research data from around the U.S. on the performance of preventive products for chafers and Japanese beetles. The number of research trials that were used in this analysis are indicated inside each bar. The product Acelepryn (chlorantraniliprole), though not shown in this graph, has also demonstrated very good control of white grubs.
