Applications
Kelpak works with the equipment already on your farm. Foliar, in-furrow, drip, seed treatment, root dip — there's a method for every operation and every season, and because it's compatible with most crop protection chemicals and foliar feeds, it goes straight into your existing programme.
Turbo mist spray.
Kelpak Liquid Seaweed Concentrate is compatible with most foliar application methods such as the various turbo fan types. Sprays vary from 2-4 pts/Ac. The ratio of Kelpak to water needs to be increased to maintain a 1:300 dilution when volumes above 1000 pts/Ac are used.
Electrostatic sprayer.
Kelpak Liquid Seaweed Concentrate can be used in electrostatic sprayers without causing clogging or blockages. Electrostatic sprayers are mostly used in table grapes at a rate of 4-5 pts/A, and applied in about 10-15 gal water/Ac.
Drip irrigation.
Kelpak Liquid Seaweed Concentrate is applied using drip irrigation methods. Apply as pulse at the end of irrigation cycle and do not dilute more than 1:1000.
Aerial application.
Kelpak Liquid Seaweed Concentrate can also be used in standard aerial applications. Standard rates for foliar application apply. Usually aerial sprays are applied in approximately 8 gallons water per acre.
Root soak.
Bare roots from trees or plants can be soaked in a Kelpak Liquid Seaweed Concentrate solution of 1% before plant out.
Soil drench.
Kelpak Liquid Seaweed Concentrate can be applied as soil drench around the root base of trees and plants or seedbeds in a 0.5-1% solution.
Seed treatment.
Kelpak Liquid Seaweed Concentrate is highly effective as a direct seed dip for coating before planting. Seed coating is recommended at a rate of 6–8 fl oz/cwt of seed.
In furrow spray.
Kelpak Liquid Seaweed Concentrate can be used as an alternative to dipping, one can spray seed with Kelpak Liquid Seaweed Concentrate at a rate of 1-2 pt/Ac directly in the furrow with planter equipment.
Seedling tray dip.
Kelpak Liquid Seaweed Concentrate can be used as seedling tray dip. Immerse seedling tray in a 1% solution or apply as a light hand-watering.
