Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

There has been a tremendous amount of scrutiny put on the neonicotinoid class of chemistry in recent years because of the potential link to declines in bee numbers. Researchers are working feverishly across the nation and the globe to determine the exact causes of bee decline. No doubt pesticides can and likely play a role to some degree, but there are many factors that also influence bee health such as habitat loss, Varroa mites, and diseases. . . . → Read More: Do Neonicotinoid Seed Treatments Have Value Regionally in Soybeans?

Insect Trap Counts, August 29, 2014

Bollworm pheromone catches were lower again for the second consecutive week, suggesting that once control is achieved for current larval populations, a major reinfestation is unlikely. Tobacco budworm catches were also lower . . . → Read More: Insect Trap Counts, August 29, 2014

Insect Trap Counts, August 22, 2014

This week’s bollworm trap catches were similar to slightly higher than last week, while tobacco budworm trap catches fell slightly for the week. The trap catches are typical for this time of year, so expect moderate worm pressure in all . . . → Read More: Insect Trap Counts, August 22, 2014

Bean Leaf Beetle Numbers Picking Up in Mississippi Soybeans

BLB_pod_feeding

Bean leaf beetle numbers have been increasing steadily over the last couple weeks. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding. Bean leaf beetles were once very easily controlled by very low rates of pyrethroid . . . → Read More: Bean Leaf Beetle Numbers Picking Up in Mississippi Soybeans

Insect Trap Counts, August 14, 2014

After 4 weeks of high bollworm moth catches averaging more than 75 moths/trap/week, this week has dropped down to an average catch of 35 moths/trap. This should mean that once current worm populations are controlled, a substantial reinfestation is not likely. However, tobacco budworm moth catches did not go down much this week, so late soybeans and non-Bt cotton could have mixed . . . → Read More: Insect Trap Counts, August 14, 2014

Insect Trap Counts, Aug. 1, 2014

Bollworm moth catches continued to be high across the state for the 3rd week in a row as the larvae that developed in corn continue to emerge. Expect significant bollworm larval pressure in vulnerable crops. Tobacco budworm moth catches rose in the Delta this week. Southwestern corn borer moth generation has now past and numbers are . . . → Read More: Insect Trap Counts, Aug. 1, 2014

Insect Trap Counts, July 25, 2014

Bollworm counts remain at fairly high levels again this week for the second week in a row, so vulnerable crops likely have many eggs and small larvae. Tobacco budworm counts remain low, so worms found will generally be bollworms. Southwestern corn borer trap counts  were still fairly high in the most northern counties of the state, but . . . → Read More: Insect Trap Counts, July 25, 2014

Trap Counts, July 18, 2014

Bollworm moth counts were up sharply across the state this week, so higher bollworm larval pressure should be expected over the next 1-2 weeks. Southwestern corn borer counts were high in Quitman, Tallahatchie and Leflore counties, but low elsewhere. Most corn is past the vulnerable window, so only late-planted corn that has not reached dough stage should . . . → Read More: Trap Counts, July 18, 2014

Insect Trap Catches, July 3, 2014

Bollworm catches were similar to the previous week while tobacco budworm counts continue to slowly rise. Neither is particularly high for this time of year. Southwestern corn borer counts were up sharply this week, with a few traps in the Delta above treatment thresholds for non-Bt corn. However, no county average was greater than 100 moths/trap, so . . . → Read More: Insect Trap Catches, July 3, 2014

Trap Catches, June 27, 2014

Bollworm counts this week were similar to last week’s counts. Other than 1 trap in Sunflower County that caught 593 moths during the week, trap catches were all less than 100 moths/trap. Tobacco budworm catches inched higher for the second week in a row. Southwestern corn borer catches are still very low, suggesting that there is no . . . → Read More: Trap Catches, June 27, 2014
