Overview

Snails and slugs can cause significant damage to lettuce, cole crops and other leafy greens and small fruits. The dense canopy, frequent irrigation and moist environment all create an ideal habitat for mollusks to feed and propagate.

Residual Protection

Many small fruit and vegetable growers treat using baits immediately prior to or following a major rain or irrigation event. A weather-resistant blanket of protection needs to be easily accessible when the slugs and snails begin nightly feeding. Metarex offers immediate protection to plants. Innovative growers have found that using no dust Metarex with application equipment designed for banded application of granular products at low rates enables them to achieve effective control. 

Metarex provides more baiting points (pellets), at approximately 35,400 per pound. Plentiful baiting points are critical for getting rid of slugs since they often do not venture far to feed, especially less-mobile juveniles.

 

Why Metarex?

The weatherability, pellet uniformity, mold resistance, palatability, and efficacy of Metarex all contribute to its performance. Integrated Pest Management (IPM) practices incorporating Metarex at reduced rates (per label directions) have been shown to achieve effective control and reduce crop damage.

Metarex 4% Metaldehyde Bait with reduced-rate technology delivers high palatability in smaller, consistently-sized pellets. An exclusive manufacturing process blends the active ingredient homogeneously throughout the pellet, while drying and hardening the pellet. This process is similar to that used for pasta. Pellets can become wet and will re-harden, offering irrigation and mold resistance and yielding long field life. Metarex’s all-weather formula is rainfast up to 45 days under normal rainfall. Metarex’s hard pellets hold up in planting equipment and fertilizer blends.

Metarex’s no dust formula reduces bait waste, and your applicator rig and clothing do not turn blue, saving you valuable clean-up time. Metarex will not stain plant containers or potting media.

Metarex provides more baiting points (pellets) at approximately 35,400 per pound. Plentiful baiting points are critical for controlling slugs since slugs often do not venture far to feed, especially less-mobile juveniles.

Weatherabilty

Metarex’s all-weather formula is resistant to rain and watering. Pellets retain their shape longer, remaining effective and providing protection for up to four weeks. Successful preventative treatments can be made according to label directions with low rates and bait can provide protection for up to four weeks.

Mold Resistance

Metarex holds up even 10 days after treatment.

Uniformity

Metarex’s pellet size uniformity helps it achieve more consistent dispersion when applied in a band, in between rows and/or directed at the base of plants with application equipment designed for banded application of granular products. Highly visible pellets help assure proper coverage and prevent over-application.

Palatability

Metarex offers high palatability with the bait carrier favored three-to-one versus fresh lettuce and carrots in slug trials. This high palatability equals quick attraction. After feeding, slugs dehydrate and die within 2-6 days.

Application Directions - Leafy Greens

For lettuce, cole crops and other leafy greens (broccoli, Brussels sprouts, cabbage, cauliflower, cavalo broccolo, collards, kale, kohlrabi, mizuna, mustard greens, spinach, rape greens), apply Metarex at a rate of 5–25 pounds per acre (A). Use the higher rate when pest pressure is high. The maximum application rate is 25 pounds of product per acre (1.0 lb ai/A) per application. A maximum of 3 applications are permitted at a minimum retreatment interval of 14 days. See full label.  See information sheet.

Application Directions - Tomatoes

Apply Metarex at a rate of 5–25 pounds per acre (A). The maximum application rate is 25 pounds of product per acre (1.0 lb ai/A) per application. A maximum of 3 applications are permitted per growing season at a minimum retreatment interval of 14 days. See full label.  See information sheet.

Application Directions - Strawberries (Perennials only)

Apply Metarex at a rate of 6.5–25 pounds per acre (A). The maximum application rate is 25 pounds of product per acre (1.0 lb ai/A) per application. A maximum of 3 applications are permitted per growing season at a minimum retreatment interval of 14 days. See full label.  See information sheet.

Application Directions - Blue, Cane and Other Berries

For blueberries, caneberries (bingleberry, black raspberry, blackberry, boysenberry, dewberry, lowberry, marionberry, olallieberry, red raspberry, youngberry) and other berries (currant, elderberry, gooseberry, huckleberry, loganberry, lingonberry, juneberry, salal), apply Metarex at a rate of 6.5–20 pounds per acre (A). The maximum application rate is 20 pounds of product per acre (0.8 lb ai/A) per application. A maximum of 3 applications are permitted per growing season at a minimum retreatment interval of 14 days. See full label.  See information sheet.
