Vegetable Crop Insects – August 31, 2012

Friday, August 31st, 2012

Joanne Whalen, Extension IPM Specialist; jwhalen@udel.edu

Cabbage
Continue to sample for cabbage looper, diamondback larvae, fall armyworm, beet armyworm and Harlequin bug. Be sure to scout and select controls options based on the complex of insects present in the field.

Lima Beans
Continue to scout for stink bugs, lygus bugs, soybean loopers, beet armyworm and corn earworm. Moths can still be found laying eggs in fields. Be sure to sample for corn earworm larvae as soon as pin pods are present. A treatment will be needed if you find one corn earworm larvae per 6 ft-of-row.

Peppers
At this time of year, corn borer, corn earworm, beet armyworm and fall armyworm are all potential problems in peppers. So be sure to select the material that will control the complex of insects present in the field. Be sure to check local moth catches in your area by calling the Crop Pest Hotline (in state: 800-345-7544; out of state: 302-831-8851) or our webpage at http://ag.udel.edu/extension/IPM/traps/latestblt.html. We continue to see aphid populations increasing, especially in fields where pyrethroids have been used on a weekly basis. Labeled materials are only effective if applied before populations explode.

Snap Beans
You will need to consider a treatment for corn borer, corn earworm, beet armyworm and soybean loopers. Sprays are needed at the bud and pin stages on processing beans for worm control. With the diversity of worm pests that may be present in fields, be sure to scout fields and select materials that will control the complex of insects present. For the most recent trap catches in your area and to help decide on the spray interval between the pin stage and harvest for ECB control in processing snap beans, you will need to call the Crop Pest Hotline (in state: 800-345-7544; out of state: 302-831-8851) or check our website http://ag.udel.edu/extension/IPM/traps/latestblt.html and http://ag.udel.edu/extension/IPM/thresh/snapbeanecbthresh.html.

Spinach
Both webworms and beet armyworms moths are active at this time and controls need to be applied when worms are small and before they have moved deep into the hearts of the plants. Also, remember that both insects can produce webbing on the plants. Generally, at least 2 applications are needed to achieve control of webworms and beet armyworm.

Sweet Corn
Be sure that a spray is applied as soon as ear shanks are visible on plants (before you see any silk). If fall armyworms are present in the whorl, you will need multiple whorl sprays for this insect before the ear shank spray to achieve effective control and to prevent larvae from dropping into the ear zone. Once fields are silking, you will need to check both blacklight and pheromone trap catches for silk spray schedules since the spray schedules can quickly change: http://ag.udel.edu/extension/IPM/traps/latestblt.html or call the Crop Pest Hotline (in state: 800-345-7544; out of state: 302-831-8851). Be sure to check all labels for days to harvest and maximum amount allowed per acre.

Upcoming Workshops Aim to Benefit Farmers with Drought-Plagued Fields

Friday, August 10th, 2012

Monday, September 17, 2012     8:00 a.m.
Paradee Center
69 Transportation Circle
Dover, DE

Monday, September 17, 2012     7:00 p.m.
Carvel Research and Education Center
16483 County Seat Highway
Georgetown, DE

Nearly 50% of the nation’s farmers’ crops have suffered losses from extremely dry conditions during the current growing season. Sharply rising prices and crop devastation will affect not just producers themselves, but all channels of the U.S. and global economies. Therefore, it is important Delaware farmers stay informed about risk management and farm safety-net options available to them, in order to keep funds available and cash flow steady.

Two workshops are to be held on September 17, 2012 featuring discussion and instruction on crop insurance, grain marketing, pending ag legislation, and general risk management. Admission is free and each meeting includes complementary risk management related materials and refreshments.

To register for either event please call 302-424-8340 or 877-673-2767 (registration is not required, but ensures availability of materials for all attendants). Setting aside the time to attend may save you time and money in the future.

UD Extension Tour and Discussion Improving Soil Health / Cover Crops for Agronomic and Commercial Vegetables

Thursday, August 2nd, 2012

Thursday, September 13, 2012   4:00 – 8:00 p.m.
Carvel Research and Education Center
16483 County Seat Hwy
Georgetown, DE 19947

Come see and hear about many of the UD Extension’s field research projects for Agronomic and Commercial vegetables which involve soil health or cover crop components.

A variety of projects will be presented including:

● Reduced tillage/no-till for limas

● Evaluation of biofumigant and winter kill cover crops

● Pumpkins produced with rye cover crop – influence of rye on weed control and fruit quality

● Use of cover crop and reduced tillage in a rotational system for commercial vegetable production – strategies for fitting cover crops into different systems

● Soybean production with rye cover crops – advantages and challenges

● Also discussion of on-going projects with bee pollination and irrigation

Dinner will be served.  There is no charge for this field day.

After dinner we will have a conversation on our current and future research efforts and would like feedback on future educational programs

Please pre-register by contacting Karen Adams at 302-856-2585 ext. 540 or adams@udel.edu.  Register by September 11.
