Storage And Disposal

PRODUCT STORAGE: Avoid exposure - obtain special instructions before use. Use care in handling / storage. Store this product in tightly closed original container in a well-ventilated place and in accordance with local / regional / national / international regulations. Keep away from food, drink and animal foodstuffs.

Avoid freezing. Store at temperatures between 32 to 100°F (0 to 38°C) and avoid contact with water. If the product is subjected to temperatures below 32°F (0°C) for an extended period of time, it will become gel-like and the formation of crystals will result in the bottom of the container. If this occurs, move product to a warm location where the inside temperature of the product can be brought above 58°F (14°C). At this point the product will return to its normal liquid state. Following these procedures the product may be used normally. No degradation of active ingredient will occur with the product that has been frozen.

Avoid high temperatures. Long term storage at temperatures above 100°F (36°C), and long term storage of open containers, will cause the product to degrade. As the product degrades, it can release harmful gases. Store below 100°F (36°C) and use opened containers within 30 days. Always use oldest stock first.

PRODUCT DISPOSAL: Follow all governmental requirements for the disposal of agricultural spray solutions.

CONTAINER DISPOSAL: Dispose according to Federal, State, provincial, and local regulations. Dispose of containers after rinsing. Cold temperatures, hard water or less than adequate amounts of water in rinsing may result in the formation of crystals. Offer empty containers for recycling, reconditioning, or dispose in a landfill or by other procedures approved by relevant authorities.
