Two new insecticides: Belay and Inovate

Posted on by

Valent U.S.A. Corporation has recently registered two new products for pest control in soybean and cotton in Virginia. Belay , has the neonicotinoid, clothianidin, as the active ingredient and is labeled for foliar applications to control aphids, plant bugs and stink bugs in cotton at 3 – 4 oz per acre, and is labeled for control of aphids, bean leaf beetles, Japanese beetles, leafhoppers, plant bugs, stink bugs and three-cornered alfalfa hoppers in soybean at 3 – 4 oz per acre. INOVATE, a combination of clothianidin and the fungicide, RANCONA (metalaxyl + ipconazole), is now labeled as a seed treatment for soybean to control early season insect pests and seedling disease. Belay has performed well in our cotton and soybean stink bug research trials. We have not evaluted INOVATE, but will be this coming field season. Contact us if you have any questions regarding these new options.

Soybean looper problems in Northampton County

Posted on by

A lot of soybean fields in Northampton County, particularly in the Cape Charles area, suffered some late-season defoliation from soybean looper. There was a lot of concern about insecticide resistance in this often difficult-to-control pest, particularly after loopers appeared in fields after being sprayed with a pyrethroid. After hearing reports from some growers and cooperators and their experiences, pyrethroids such as Baythroid and Warrior, were effective against this pest if you got good coverage and penetration into the canopy. Also, follow-up sprays of Warrior appeared to clean up the larvae in some of the problem fields. It is more than likely that some of the soybean looper infestations that we had on the soybeans in Northampton County following sprays of Warrior or another pyrethroid were a result of poor coverage or possibly bad timing. It would have been very difficult for a low volume aerial application to penetrate all of the foliage that we had on our dense soybean canopies this year in Northampton County. It is possible that soybean loopers fed on untreated leaves in the lower canopy, then moved on to the pesticide covered upper foliage after the residual was gone.

Insect Trap Counts for the Eastern Shore for Week ending Sept 18, the season finale

Posted on by

Folks, this is the final insect pest trap data for 2009 for the Eastern Shore. We’ve pulled up all of the blacklight and pheromone traps.
In general, there is still a little bit of moth activity of corn earworm and beet armyworm, and fall armyworm has increased on the Shore. Blacklight trap counts for this week were as follows: David Long (Cape Charles) = 25 corn earworm, 7 beet armyworm, 4 fall armyworm, 4 green stink bug. Blacklight trap – Mark Colson (Eastville) = 14 corn earworm, 10 beet armyworm, 13 Fall armyworm; 0 green stink bugs, 1 brown stink bugs. Blacklight trap Painter = 8 corn earworm moths, 8 beet armyworm, 3 fall armyworm, 16 green stink bugs, 0 brown stink bugs. ******************************************Corn earworm Pheromone Traps (weekly catch): Keller = 8; Tasley = 0; Modesttown = 1 ; New Church = 3; Horntown = 2; Eastville = 25; Machipongo = 9 ; Painter = 3; Guilford = 0. Beet armyworm Pheromone traps (weekly catch): Modestown = 0; New Church = 1; Horntown = 12; Machipongo = 53 (increase); Painter = 1. Fall armyworm pheromone traps (weekly catch): Painter: 75(big increase); Newman – Eastville: 29 (increase); Hortntown: 28 (increase). ****************************************************************************************Summary, corn earworm and beet armyworm moths are still flying on the Eastern Shore, and are likely still depositing eggs on whatever green plants they can find. Late planted beans, fruiting vegetables and cole crops are prime host crops this time of year for both species. We’ve also observed an increase in fall armyworm moths at every location on the Eastern Shore. This pest can attack a wide range of vegetable host plants as well, and can even be a pest of turf.

Insect Trap catch on the Eastern Shore for Week Ending Sept 18

Posted on by

Insect Trap Counts for the Eastern Shore for Week ending Sept 18. Moth activity picked up a little bit from the previous rainy last week. Blacklight trap counts for this week were as follows: David Long (Cape Charles) = 22 corn earworm, 5 beet armyworm, 4 fall armyworm, 1 green stink bug (very low). Blacklight trap – Mark Colson (Eastville) = 31 corn earworm, 9 beet armyworm, 6 Fall armyworm; 12 green stink bugs, 1 brown stink bugs. Blacklight trap Painter = 27 corn earworm moths, 15 beet armyworm, 15 fall armyworm, 36 green stink bugs, 3 brown stink bugs. ******************************************Corn earworm Pheromone Traps (weekly catch): Keller = 0; Tasley = 0; Modesttown = 1 (drop); New Church = 1; Horntown = 0; Eastville = 16; Machipongo = 3 (big drop); Painter = 3; Guilford = 1. Beet armyworm Pheromone traps (weekly catch): Modestown = 3; New Church = 2; Horntown = 24; Machipongo = 27; Painter = 20. Fall armyworm pheromone traps (weekly catch): Painter: 11; Newman – Eastville: 0; Hortntown: 2. ****************************************************************************************Summary, corn earworm moth activity appears to be finally dropping off on the Eastern Shore. Corn earworm, beet armyworm, and fall armyworm moths are still flying on the Eastern Shore and laying eggs on crops. Tomatoes in Painter at the ESAREC had above threshold numbers of new eggs on leaves this week. Sprays for “worm” pests are advised. Beet armyworm larval activity has also been seen in tomatoes and peppers. Stink bugs are present, but not in high numbers in late-planted soybean fields. Soybean loopers have been reported as a big pest problem in lower Northampton County. This insect pest appears to have survived the preventative pyrethroid sprays on many soybean fields, and may need some different insecticide classes to kill it, such as Steward, Tracer, Lannate, or Larvin, or Intrepid. The new Cobalt insecticide from Dow would likely also control soybean looper.
