MUSHROOMS - SPAWN GRAINS

General Information

PRODUCT INFORMATION

Mertect 340-F is a systemic fungicide which aids in the control of many important plant diseases. If treatment is not effective following use of Mertect 340-F as recommended, a tolerant strain of fungus may be present. Consideration should be given to prompt use of other suitable non-benzimidazole fungicides. Mertect 340-F is not for use in formulating agricultural products.

RESISTANCE MANAGEMENT

This product contains Thiabendazole, a Group 1 fungicide. Thiabendazole belongs to the methylbenzimidazole carbamate class of chemistry which disrupts s-tubuline assembly in mitosis.

Fungal pathogens can develop resistance to products with the same mode of action when used repeatedly. Because resistance development cannot be predicted, use of this product should conform to resistance management strategies established for the crop and use area. Consult your local or State agricultural authorities for resistance management strategies that are complementary to those in the label. Resistance management strategies may include alternation and/or tank-mixing with products having different modes of action or limiting the total number of applications per season.

Syngenta encourages responsible product stewardship to ensure effective long term control of the fungal diseases on the label.

CROP USE DIRECTIONS

GENERAL - SHAKE OR STIR WELL BEFORE USE.

Clean equipment before using Mertect 340-F. When Mertect 340-F is dispersed in water, the resulting suspension must be constantly agitated. Avoid foaming.

Use the higher specified rates under conditions of heavier disease pressure.

Compatibility information for Mertect 340-F with other chemicals is limited. Consult your supplier or agricultural experiment station for specific recommendations.

Restrictions and Limitations

- Maximum one application per season.

- This product must not be tank mixed with any pesticide unless physical compatibility and phytotoxicity tests have been completed and proved to be satisfactory.

- Regardless of type of application, do not apply more than 0.15 lb thiabendazole per acre (68.0 grams ai/A) per year.

- Do not feed vines or hay of Dry Peas (chickpea, field pea, lentil and pigeon pea) grown from seed treated with Mertect 340-F to livestock.

Limitations, Restrictions, and Exceptions

Mushrooms (Agaricus spp.) - Dry Bubble (Verticillium fungicola), Wet Bubble (Mycogone perniciosa), Cobweb (Dactylium dendroides) and Green Mold (Trichoderma spp.):

FOR USE AS AN ADMIX WITH MUSHROOM SPAWN GRAINS, MUSHROOM GROWING SUPPLEMENT, AND/OR AS A DRENCH DURING NORMAL WATERING OPERATIONS FOR MUSHROOM GROWING BEDS AT CASING OR BETWEEN BREAKS

NOTE: Do not exceed a combined total of 20 fl oz per 1,000 sq ft of product, between the various applications to spawn grains, supplement, and mushrooms. This amount may be used in various treatment regimes. Please refer to the tables in the label for the rates for the various usage so that the 20 fl oz per 1,000 sq ft is not exceeded.

Spawn Grains: Apply a maximum of 5.4 fl oz of Mertect 340-F per 1,000 sq ft. Follow the table below to determine the fl oz of Mertect 340-F that can be mixed with the spawn to deliver 5.4 fl oz per 1,000 sq ft.

Use on Spawn Grains

Do not apply Mertect 340-F to gypsum, limestone, or chalk. Admix Mertect 340-F directly onto spawn grain.

Mushroom Supplements: A fi nished batch of mushroom supplement can contain up to 0.1% Thiabendazole (by weight). The Thiabendazole added to the supplement must be included as part of the total of the 20 fl oz of Mertect 340-F allowed per 1,000 sq ft per crop. The total amount of Mertect 340-F that can be applied from all treatments per crop is dependent on the amount of supplement applied (use the table in the label to determine the remaining volume of Mertect 340-F that can be applied per crop).

- Assumes at maximum rate of 0.1% Thiabendazole.

The amount added for supplement treatment must be deducted from the total remaining amount that can be applied to mushrooms so as not to exceed 20 fl oz per 1,000 sq ft per crop.

Note: If you are unsure if the mushroom supplement that you are using contains Thiabendazole, contact the manufacturer of the mushroom supplement.
