indefinitely as long as they are composed of materials to prevent deterioration and maintain legibility for the duration of the posting period.
•All words shall consist of letters at least 2 1/2 inches tall, and all letters and the symbol shall be a color which sharply contrasts with their immediate background. At the top of the sign shall be the words “KEEP OUT”, followed by an octagonal stop sign symbol at least 8 inches in diameter containing the word “STOP”. Below the symbol shall be the words “PESTICIDE IN IRRIGATION WATER”.
•Posting required for chemigation does not replace other posting and reentry requirements for farm worker safety.
REPLANTING (FOLLOWING ALFALFA)
•Do not replant treated areas to any crop except corn, root crops or sugarcane within two years after treatment, as crop injury may result.
•Corn may be planted 12 months after the last treatment in areas of moderate to high rainfall (greater than 20 inches), provided the use rate did not exceed 3 pints per acre.
•Root crops such as potatoes, sugarbeets, radish and carrots may be planted 12 months after last treatment, provided the use rate does not exceed 2 pints per acre. Sites with use rates higher than 2 pints per acre should not be replanted to any root crop within 2 years after application of DuPont™ VELPAR® L, or unacceptable crop injury may result.
In areas where irrigation is needed to produce the crop, the crop rotation intervals listed may need to be extended if the normal irrigation amount is reduced for any reason.
•Sugarcane may be planted any time following treatment.
•In California, do not replant seed alfalfa areas to any crop within two years after treatment, as crop injury may result.
FLOOD IRRIGATED ALFALFA
In arid climates (10 inches of rainfall or less per year) or areas where drought conditions have prevailed for one or more years, a field bioassay should be completed prior to planting any desired crop. The results of this bioassay may require the rotation intervals listed above to be extended.
A successful bioassay means growing to maturity a test strip of the crop(s) intended for production. The test crop(s) strip should cross the entire field including knolls, low areas, and areas where any berms were located.
In areas where irrigation is needed to produce the crop, the crop rotation intervals listed may need to be extended if the normal irrigation amount is reduced for any reason.
ALFALFA - IMPREGNATION ON DRY BULK FERTILIZER (EXCEPT CALIFORNIA AND ARIZONA)
Dry bulk fertilizer may be impregnated or coated with VELPAR® L for application to established alfalfa. All recommendations and precautions on this label must be followed along with state regulations relating to dry bulk fertilizer blending, impregnating and labeling.
If fertilizer materials are excessively dusty, use a suitable additive to reduce dust prior to impregnation, as dusty fertilizer will result in poor distribution during application. The dry fertilizer must be properly impregnated and uniformly applied to the alfalfa to avoid crop injury and/or poor weed control.
To impregnate the fertilizer, use a system consisting of a conveyor or closed drum used to blend dry bulk fertilizer. Any commonly used fertilizer can be impregnated with VELPAR® L, except potassium nitrate or sodium nitrate. Do not use VELPAR® L on limestone.
Use a minimum of 250 lb dry bulk fertilizer per acre and up to a maximum of 450 lb per acre. To impregnate or coat the dry bulk fertilizer with VELPAR® L, direct the nozzles to deliver a fine spray of this suspension toward the fertilizer for thorough coverage while avoiding spray contact with mixing equipment. Uniform impregnation of VELPAR® L to dry bulk fertilizer will vary, and if the absorptivity is not adequate, the use of an absorptive powder may be required to produce a dry,
Apply impregnated fertilizer as soon as possible after impreg- nation for optimum performance.
Select the rate of VELPAR® L to apply per acre from the appropriate section of this label. Then refer to the rate chart below to determine the amount of VELPAR® L that should be impregnated on a ton of dry bulk fertilizer, based on the amount of fertilizer to be distributed in one acre.
