Kobra

A highly effective pesticide wetting and spreading agent for use in agricultural, horticultural and forestry crops. As a foliar adjuvant Kobra acts as a wetting, spreading and penetrative agent. As a growing media adjuvant Kobra can be used to wet or re-wet all growing media and soils.

Crops
All agricultural, horticultural and forestry crops.

Use
1. To improve foliar uptake of acaricides, fungicides, insecticides and foliar nutrients through better distribution and faster drying
2. As a dry wash to reduce visible residues prior to harvest or sale
3. As a growing media wetter/re-wetter, through drip or overhead irrigation, or as a drench

Pack Sizes
5, 200, 1000 litres

Composition
A water-miscible concentrate of modified fatty amine and sugar derivatives.

Kobra is a fatty amine based wetter designed to give enhanced coverage and consequent uptake of agrochemicals and foliar nutrients when used as a foliar adjuvant. The improved coverage means drying time is usually 50% quicker than agrochemicals alone.
Kobra reduces stains caused by deposition of salts left on leaves from hard water, foliar nutrients and chemicals. When used as a dry wash Kobra significantly improves the visual appearance of fruits and leaves if applied just prior to harvest or sale. It is particularly suitable for protected edibles, cut flowers and ornamentals.
When applied as a growing media wetter/re-wetter, Kobra will give even penetration throughout the growing media and soil. Kobra will provide even wetting and re-wetting of growing media reducing surface tension of the irrigated liquid. The result is smaller or no dry patches as well as less risk of shrinkage. Laboratory tests have shown similar wetting performance to the industry standard.
 

Kobra can be used alone or mixed with a wide range of acaricides, fungicides, insecticides and foliar nutrients. If using as a pesticide adjuvant, always read the appropriate pesticide label before use.
Use the dilution rates below. For foliar applications with agrochemicals use the water volume per hectare recommended on the pesticide label.
