Sevin 80S was applied with a hand-pumped compressed air sprayer to the point of runoff. Sevin XLR Plus was applied with an ultra-low volume applicator at 1 part XLR in 11 parts water and 1 part XLR in 39 parts water. Treatments were evaluated by counting the number of beetles feeding ...
Japanese beetles destroy vegetation at two stages of their lives. Immature beetles (called “grubs”) destroy lawns by eating grass roots and thatch, as well as the roots of bean, corn, strawberry, and tomato plants. These youngsters are difficult to get rid of because they live underground u...
Japanese beetles live around one year. Eggs hatch in the fall, feed before winter and then overwinter by going deep into the soil below the frost line. In the spring, they will come back up to the top of the soil, pupate to adults and then emerge as the flying pest we all love to ...
for control of Japanese beetle grubs. The fairway consisted of annual bluegrass (30%) and Kentucky bluegrass (70%). Treatment plots were 10 by 10 ft, arranged in a RCB design and replicated three times. Liquid formulations were applied in 3 gal of water with a hand-held sprinkling can. ...

Some species, like Japanese Beetles, prefer egg-laying in areas with specific cultivars (i.e. turf) while feeding on a wide range of other hosts as adults. Life Cycle: Eggs can be laid in the soil, on grain, on leaves, on seeds, or in plants themselves. Larvae feed voraciously once ...
Japanese Beetle grubs in about a week after infection. As the grub decomposes, the billions of spores it contained are released back into the soil to start the whole process again. Over time, Milky Spore fills out the soil creating a soil environment that Japanese beetles simply cannot survive...
Field-based bioassays assessed adult mortality and knockdown, and fruit and leaf injury from Japanese beetles exposed to 4-h and 7-d field-aged residues of imidacloprid, and the conventional insecticides azinphosmethyl and esfenvalerate. Azinphosmethyl and imidacloprid caused high levels of mortality ...
