AGRISPON ® Instructions to Use

Agrispon may be used on all food, feed and row crops, consistent with the use directions and restrictions stated below. Agrispon may also be used for horticultural applications, as noted below.


Apply Agrispon via boom, fan jet, hand carried, or backpack spray equipment. This product may be applied through drip and overhead irrigation systems. Follow all chemigation directions below. Shake well before using. Agitate solutions either during or immediately after dilution. Apply solution within eight hours of mixing. Dilute Agrispon in water as specified in the table below:

*The table specifies the minimum amount of water to be used; Agrispon may be diluted in a larger volume of water if desired. The amount of water used will vary according to equipment, type of nozzle used, number of nozzles, ground speed’ system pressure, and calibration. If soil is covered with plant material, mulch, or thatch, use sufficient water to transport it to the soil during application or lightly irrigate after application. Rates of application are based on use in North America. Different climates and soils may require adjustments.

» Short cycle - (growth cycle of 60 days or less)
Make single application at, or as soon after planting as possible. Maximum number of applications/area/year: 6

» Mid season Plants - (growth cycle of 60 to 120 days)
Make first application at planting or within two weeks of germination with a subsequent
application 45 to 60 days after. Maximum number of applications/area/year: 6

» Long Season
– (growth cycle longer than 120 days)
Make an initial application at planting or within two weeks of germination. Make subsequent applications at 45 to 60 day intervals during the period when plant is growing vigorously. Maximum # of applications/area/year: 8


Apply to the soil surface extending out 3 to 4 times the distance of the trunk to drip line to insure root coverage.

» Evergreen:
For newly planted perennials, initial application should be made at, or as soon after planting as possible. For established perennials, initial application should be made when soil temperature warms to 50°F. For climates where soil temperatures are >50°F year round, initial application may be made at any time. Application should be repeated every 60 days as weather permits. Maximum number of applications/area/year: 6.

» Deciduous:
Make first application at bud break or leaf flush in the spring. Make subsequent application every 60 days until dormancy occurs. Maximum number of applications/area/year: 6.


Apply every 6 to 8 weeks during active growth. Number of applications will depend on the growth cycle length as explained above.

Apply this product only through drip (trickle) or sprinkler, including center pivot, lateral move, end tow, side (wheel) roll, traveler, big gun, solid set, or hand move irrigation systems. Do not apply this product through any other type of irrigation system.
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution of treated water. If you have questions about calibration, you should contact State Extension Service Specialists, equipment manufacturers or other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesticide label-prescribed safety devices for public water systems are in place. A person knowledgeable of the chemigation system and responsible for its operation or under the supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise.


The following instructions apply to all chemigation methods discussed on this labeling.
Determine the number of acres to be treated by the chemigation system. Prepare a premix by adding the recommended volume of AGRISPON from the table above and a minimum of one gallon of water for each acre to be treated into a reservoir container. The use of larger quantities of water to dilute the premix may make calibration of the application easier. Meter the premix into the chemigation system at a rate that will consume the entire premix within the period of chemigation or within 8 hours, whichever is less. Maintain agitation in the reservoir during the period of chemigation to keep material in suspension.
