Dear Mr. Stay: 
 
The Agency, in accordance with the Federal Insecticide, Fungicide and Rodenticide Act 
(FIFRA), as amended, has completed reviewing all of the information submitted with your 
application to support the Registration Review of the above referenced product in connection 
with the December 2021 Metaldehyde Interim Decision, and has concluded that your submission 
is acceptable. The label referred to above, submitted in connection with registration under 
FIFRA, as amended, is acceptable. 
 
Should you wish to add/retain a reference to the company’s website on your label, then please be 
aware that the website becomes labeling under the Federal Insecticide Fungicide and Rodenticide 
Act and is subject to review by the Agency. If the website is false or misleading, the product 
would be misbranded and unlawful to sell or distribute under FIFRA section 12(a)(1)(E). 40 
CFR 156.10(a)(5) list examples of statements EPA may consider false or misleading. In addition, 
regardless of whether a website is referenced on your product’s label, claims made on the 
website may not substantially differ from those claims approved through the registration process. 
Therefore, should the Agency find or if it is brought to our attention that a website contains false 
or misleading statements or claims substantially differing from the EPA approved registration, 
the website will be referred to the EPA’s Office of Enforcement and Compliance. 
 
A copy of your label stamped “Accepted” is enclosed. Products shipped after 12 months from the 
date of this amendment must bear the new revised label. Your release for shipment of the 
product bearing the amended label constitutes acceptance of these conditions. If these conditions 
are not complied with, the registration will be subject to cancellation in accordance with FIFRA 
section 6.

This pesticide is toxic to mollusks (e.g., clams, oyster s, scallops, mussels). Do not apply directly to water, 
to areas where surface water is present, or to intertidal areas below the mean high water mark. Drift and 
runoff may be hazardous to aquatic organisms in wate r adjacent to treated ar eas. Do not contaminate 
water when disposing of equipment wash waters or rinsate. 
 
This pesticide is toxic to birds and mammals. Granul es on soil surface may be hazardous to terrestrial 
wildlife. Cover or collect any such materials spilled during loading.

91-20220831 Page 4 of 8 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeli ng and with the Worker Protection Standard, 40 CFR, 
Part 170. This standard contains requirements for the protection of agricultural workers on farms, forests, 
nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, 
decontamination, notification, and emergency assistan ce. It also contains specific instructions and 
exceptions pertaining to the statements on this label about personal protective equipment (PPE) and 
restricted-entry interval (REI). The requirements in this box only apply to uses of this product that are 
covered by the Worker Protection Standard. 
 
Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 12 hours. 
Exception: if the product is soil -injected or soil-incorporated, the Worker Protection Standard, under 
certain circumstances, allo ws workers to enter the treated areas wi thout restriction if there will be no 
contact with anything that has been treated. 
 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and 
that involves contact with anything that has been treated, such as plants, soil, or water, is: 
x Coveralls 
x Chemical-resistant gloves 
x Shoes plus socks 
 
RESTRICTIONS 
This product is intended solely for use on agricultural crops grown for commercial or research purposes 
and in State and/or Federal invasive mollusk eradication operations. This product may not be applied to 
residential sites (i.e., in yards, gardens, around homes and apartments) and other sites such as the exterior 
areas around schools and daycare facilities, and athletic fields, playgrounds, parks, recreation areas, etc. 
 
Broadcast applications and applications of this product directed to plant parts are prohibited except to 
grass grown for seed and as specified for use in State and/or Federal inva sive mollusk eradication 
operations. 
 
Read entire label before using. Use only as a bait ing treatment to be applied directly to the soil area 
beneath plants as listed on this label. Do not allow bait granules to come in contact with plants. The 
grower is responsible for residues on his crops, as well as for damages caused by drift from his property 
to that of others. Do not allo w drift to adjoining food, fiber or pasture crops. NOTE: DURHAM 
METALDEHYDE GRANULES 3.5 should never be applied to dry soil. For best results irrigate prior to 
application. Apply any time of the day but evening applications are preferred for increased snail or slug 
control. Do not re-water for 48 hours after application. 
 
Advisory Resistance Management for Molluscicides 
For resistance management, DURHAM METALDEHYDE GR ANULES 3.5 contains metaldehyde, a systemic 
molluscicide that eliminates pests by destroying the mucus-producing glands of mollusks resulting in 
dehydration. 
 Naturally occurring biotypes resistant to metaldehyde-based baits may still develop and 
become dominant after repeated use. Appropri ate resistance-management strategies should be 
followed. 
 
The following steps can be used to delay the development of resistance: 
x Rotate pest control methods when possible 
x Use this product strictly in accordance with th e label. Monitor after application for unexpected 
target pest survival. If the level of survival suggests the presence of resistance, consult with the 
manufacturer, your local university specialist or certified pest control advisor.

91-20220831 Page 5 of 8 
x If a pest population continues to persist after treatment with this product, discontinue use of this 
product, and switch to another management strategy, if available. 
x If pest resistance is observed or suspected, please report to AMVAC Chemical Corporation at 1-
888-462-6822. 
 
USE INFORMATION 
Snails and slugs are nocturnal and generally feed during the night damaging many varieties of plants and 
plant seedlings. They inhabit damp, moist areas around decaying refuse, organic matter, beneath rocks 
and hide at the base of growing plants. Their presence can be detected by the shiny trails left on the soil 
surface, sidewalks, driveways, etc. 
 
APPLICATION RATES 
For control of SNAILS and SLUGS in the following ar eas, apply when first plant damage appears or is 
anticipated. 
 
Apply at the rates specified for each crop to areas likely to be infested at the beginning of the planting 
season or during periods of damp weather before damage occurs. For best re sults, apply in evening. 
Especially beneficial if applied following rain or watering since slugs and snails will not crawl over dry soil. 
 
Prior experience has shown most plants are not sens itive to Durham Metaldehyde 3.5. However, for 
extremely tender plants such as orchids, it is sugge sted to do a small test application to determine any 
plant sensitivity before making applications to plants. 
 
For use on ornamentals, artichokes, blueberries, can eberries, strawberries, lettuce, cole crops and other 
listed leafy greens, mint, corn, soybeans and tomatoes apply in a band, between rows and/or directed 
towards base of the plants, by hand or with commercial application equipment designed for banded 
application of granular products. 
 
For use on citrus, apply in a band under tree canopy, by hand or with commercial application equipment 
designed for banded application of granular products. Do not apply as a wide area broadcast.

3Broadcast application to be made under flooded conditions only. Prior to bait application, stop the water flow into and out of the 
lo’I (paddies) to be treated; water level should be high enough such that apple snails don’t estivate. Apply the bait and hold/impound 
the water for a minimum of 3 days before allowing water to ex it the lo’i. Do not apply more than one application per 
held/impounded water. If the water level in the lo’i becomes too low within the 3 day holding period (due to faster percolation of 
water through the soil), such that apple snails begin to estivate, allow additional water into the lo’i. 
 
For corn and soybean apply as a perimeter treatment at planting and then for the subsequent applications 
by broadcast directing the product to the soil.
