For use only on field corn, production seed corn, silage corn, sweet corn, popcorn, Miscanthus and other non-food perennial bioenergy crops. Corn in this label refers to: field corn, production seed corn, silage corn, sweet corn and popcorn. Keystone NXT herbicide may be applied to the surface or incorporated into the top 1-2 inch layer of soil. It may be used for control alone, or in tank mix combinations, for the weeds listed in the "Target Weeds" section of these use directions.

Use Restrictions
• Not for Sale, Sale Into, Distribution and/or Use in Nassau and Suffolk Counties of New York State.
• This chemical demonstrates the.properties and characteristics associated with chemicals detected in ground water. The use of this chemical in areas where soils are permeable, particularly where the ground water is shallow, may result in ground water contamination.
• Do not apply Keystone NXT before pre-irrigation in irrigated areas.
• Do not allow Keystone NXT to contaminate feed or food.
• Do not contaminate irrigation water used for crops other than corn or water used for domestic purposes.
• Do not use Keystone NXT on any crop other than field corn, production seed corn, silage corn, sweet corn, popcorn, and Miscanthus or other non-food perennial bioenergy crops.
• On the following soil types, do not apply this product within 50 feet of any well where the depth to groundwater is 30 feet or less: sands with less than 3% organic matter; loamy sands with less than 2% organic matter; or sandy loams with less than 1 percent organic matter. See the figure for additional clarification.

Use Precautions
• Failure to strictly follow label directions may result in exceeding the maximum annual atrazine use rates as stipulated by the Environmental Protection Agency.
• Note: This product contains atrazine and thus may not control weeds that are known or suspected to be triazine resistant. Following many years of continuous use of atrazine and chemically related products, biotypes of some of the weeds listed on this label have been reported which cannot.be effectively controlled by atrazine and related herbicides. Where this is known or suspected and weeds controlled by atrazine are expected to be present along with resistant biotypes, it is recommended that atrazine be used in combinations or in sequence with other registered herbicides which are not triazines. If only resistant biotypes are expected to be present, use a registered non-triazine herbicide.
• Keystone NXT should not be used on corn seed stock such as Breeders, Foundation, or Increase.
• Keystone NXT should not be stored near seeds, fertilizers, or foodstuffs.
• All containers of Keystone NXT should be kept tightly closed when not in use.
• Applied according to directions and under normal growing conditions, Keystone NXT will not harm the reated crop. During germination and early stages of growth, extended periods of unusually cold and wet or hot and dry weather, insect or plant .disease attack, carryover pesticide residues, the use of certain soil applied systemic insecticides, improperly placed fertilizers or soil insecticides may create abnormal conditions that weaken crop seedlings. Keystone NXT used under these abnormal conditions could result in crop injury.
