Annual Mississippi
Greenhouse Tomato Short Course

Dr. Rick Snyder, Vegetable Specialist

If you are a grower of greenhouse tomatoes, or if you have interest in growing this crop, mark your calendar now for the 11th Annual Greenhouse Tomato Short Course. Participating in this program will be the best way to learn all about producing greenhouse tomatoes.

The 2001 Greenhouse Tomato Short Course will be at the Mississippi Agriculture & Forestry Museum, at 1150 Lakeland Drive, Jackson, MS on March 22 & 23 (Thursday & Friday). The program will be in the Sparkman Building (formerly known as the Country Music Hall of Fame). In addition, there will be 2 optional tours Friday afternoon. I am certain that you will find this year's speakers to be experts in their respective fields. Please look over the agenda included in this packet.

The first day will cover all of the basics of greenhouse tomato production - introductory information about how to grow greenhouse tomatoes, common grower problems, getting organized in your greenhouse business, a budget both for getting into the business as well as operating costs, nutrition and fertility, and all those things that you need to know to grow a good crop.

The second day will be a bit more advanced. You will learn about insect and disease identification and management, biological control, new technologies and greenhouse structures, some of the equipment and supplies you need for the greenhouse, and some other advanced topics.

Exhibitors will be available to show you their products and discus how to use them. All aspects of production will be thoroughly covered. Plan on attending this 2-day Short Course to learn all you need to know about this crop. With the rapid growth of the greenhouse tomato industry in Mississippi over the past few years, Mississippi is one of the leading states in the U.S.

Advance registration is $75 (use registration form in this packet), or if your prefer you can pay $90 at the door (per person for both days). I would like to encourage advance registration so that the number of meals can be estimated accurately. Advance registration must be received by March 10th. The registration fee includes coffee breaks, refreshments, catered lunch both days, dinner Thursday evening, and crawfish boil Friday evening, several Extension publications, and admission to the Agriculture & Forestry Museum (inside and outdoor exhibits). And, all those who pre-register will also receive a Greenhouse Tomato Short Course cap. Complete information can also be found on the web at http://www.msstate.edu/dept/cmrec/GHSC.htm .

In this issue of Vegetable Press are the complete Agenda for the Greenhouse Tomato Short Course, as well as a registration form For further information, call Dr. Richard Snyder at (601) 892-3731, email to RickS@ext.msstate.edu, or contact your local Mississippi County Extension Office.

 

New Product for Vegetable Insect Control

Dr. J. Pat Harris
Extension Entomologist

SpinTor is a naturalyte insect control product for control of lepidoptera larvae (worms or caterpillars), leafminers, and thrips in cole crops, fruiting vegetables (tomatoes, peppers, and eggplants), and leafy vegetables. The naturalyte is derived from a fermentation process of Saccharpolyspora spinosa. SpinTor is a 2 SC (suspension concentrate) that should be mixed with water and applied as a foliar spray.

In cole crops, SpinTor will control diamond back moths, imported cabbageworms, cabbage loopers, armyworms (including beet armyworms), and leafminers. See label for rates and usages. Do not apply within one day of harvest.

In fruiting vegetable crops (eggplants, ground cherries, pepino, peppers, tomatillo, and tomatoes), SpinTor will control lepidopterous larvae, Colorado potato beetle larvae, hornworms, loopers, tomato fruitworms, armyworms, thrips (including melon and western flower), tomato pinworms, European corn borer, and leafminers. See label for rates and usages. Do not apply within one day of harvest.

In leafy vegetables, SpinTor will control cabbage loopers, armyworms, and leafminers. See label for rates and usages. Do not apply within one day of harvest. For resistance management, do not apply more than three times in a 21-day period. Rotate to a different class of insect control product or no treatment for the next 21 days.

Confirm 2F - New Product for Worm Control - Cole Crops & Leafy Vegetables

Dr. J. Pat Harris, Extension Entomologist

This is a reminder to those farmers growing cole crops and leafy vegetables. A new product from Rohm and Haas become available last year for worm control on these crops. This is sold as Confirm 2F with the active ingredient tebufenozide which mimics the action of the natural insect hormone that induces the molting process in insects. Confirm 2F is highly active against most lepidopterous larvae. It is selective in its control, allowing the buildup of populations of beneficials and predatory insects which is very important in integrated pest management programs. Premature lethal molt occurs within hours of ingestion and actual death of larvae will take several days, although feeding generally ceases within 24 hours of ingestion. The Rohm and Haas label for Confirm 2F is as follows:

USE DIRECTIONS FOR COLE CROPS, LEAFY VEGETABLES AND TURNIPS (TOPS AND ROOTS)

 Ground Application: Apply a minimum of 10 gallons per acre by conventional ground equipment to young crop and small plants. Apply a minimum of 20 gallons per acre to densely foliated or difficult-to-cover crops to ensure thorough coverage.

Aerial Application: Make applications of CONFIRM 2F in a minimum of 10 gallons per acre.

Spray Adjuvant: One pint of LATRON CS-7 per 100 gallons of spray mixture or a similar spreader-binder is recommended to maximize coverage and distribution of the spray material.

6.0 to 8.0
(0.09 to 0.12 lbs.

For early-season applications only to young crop and small plants. Begin applications when first signs of feeding damage appear or when infestations reach threshold levels as defined by Cooperative Extension Service or other qualified professional authorities.

Do not apply more than 8 fluid ounces per application and do not exceed 56 ounces product per season.

Allow at least 7 days to elapse between final application and harvest.

See Rotational Crop Restrictions.

8.0

(0.12 lbs. AI/Acre)

For mid- to late-season applications and to heavier infestations and under conditions in which thorough coverage is more difficult.

 Under heavy infestations, continuous moth flights and/or egg masses and larvae in all stages of development, re-application on a 10- to 14-day schedule will be required to protect new growth until moth flights and/or hits subside.
