Pepper Weevil Situation for 2014

Sign up for pepper weevil monitoring with the Rutgers IPM Team.  Our base fee is $450 per farm and $100 per trap deployed.  If we are already doing insect trapping or field scouting at a farm, then the only additional cost is for the weevil pheromone traps.  We suggest that one trap be set in a high traffic area near the packing shed and then at least one trap per field.

For more information or to sign up for weevil monitoring, contact Joe Ingerson-Mahar, phone – 856-889-5718, or email, mahar@aesop.rutgers.edu 

For the past two years we have had two NE-SARE grants and a grant from the Charles and Lena Maier Fund, New Jersey Vegetable Growers Association, to study the movement of pepper weevil within New Jersey and how it arrives here.  This article summarizes our findings and what the situation is for 2014.

Early-season Pythium and Phytophthora Control in Pepper & Tomato

With the wet spring we’ve had thus far, it’s easy to see the potential for Pythium and Phytophthora problems to develop once transplanting begins.

Unlike in the past, there currently are a number of good options for early season control of these pathogens, it just takes a little bit more planning ahead of time.

Options for pre-transplant applications include a Ranman (cyazofamid, 21) drench one week before transplanting for Pythium in tomatoes; as well as Previcur Flex (propamocarb HCL, 28) for the suppression of Pythium and Phytopthora in tomatoes and peppers. Phosphite fungicides, such as ProPhyt, Rampart, and K-Phite (FRAC code 33) can also be applied as a pre-transplant drench in the greenhouse on many crops. [Read more…]

Phytophthora crown and spear rot – In fields with low spots (poorly drained soils) or fields with a history of crown and/or spear rot apply Ridomil Gold 4SL (mefenoxam, 4) at 1.0 pt/A, or Ultra Flourish 2E/A (mefenoxam, 4) at 2.0 pt/A, or MetaStar 2E (metalaxyl, 4) at 2.0 qt/A over beds just before 1st harvest. For new plantings, apply the same after planting or after crown covering. Do not apply Ridomil or MetaStar one day prior to harvest or illegal residues may result. For more information please see 2014 New Jersey Commercial Vegetable Production Recommendations Guide. [Read more…]

Controlling Septoria Leaf Spot in Parsley

Septoria leaf spot (SLS) in Parsley can cause significant losses in fields where it has become established. Like other Septoria’s, the leaf spots produced on parsley look much like the leaf spots produced on tomatoes and other crops. Septoria leaf spot overwinters from year to year on infected debris so long crop rotations of 2 or more years are important to help reduce disease pressure. During the season, SLS will spread rapidly with each subsequent rainfall and/or overhead irrigation event. Therefore, early detection and preventative fungicide applications are key to successfully controlling SLS. Unfortunately, very few fungicides are currently labeled making control difficult.

Lettuce Weed Control

Work continues to progress toward reinstating the Kerb label for leaf lettuce, but has not been completed and is not expected to be completed in time for use in this year. [Read more…]
