GENERAL INSTRUCTIONS

MIXING

Add a few mLs of VADER 225 VeripHy to a sample of water to be used in the spray solution preparation and mix thoroughly.

If a yellow colouring is exhibited, this signals that the spray solution is weakly acidic to neural (4 < pH < 7) and hydrolysis is not a threat with no further action needed. Progress directly to spray solution preparation at full scale.

If a green colouring is exhibited, this signals that the spray solution is alkaline (pH > 7) and alkaline hydrolysis is a threat. The spray tank dilution water requires treatment with an acidifying agent. Imtrade Pro 700 Surfactant (APVMA Product No. 64260) or an equivalent product should be added in line with label directions to reduce the pH to a preferred level and preserve Acetamiprid. After acidification, retest the dilution water by adding a few mLs of VADER 225 VeripHy and only progress to spray solution preparation at full scale when a yellow colouring is exhibited.

If an orange colouring is exhibited, this signals that the spray solution is strongly acidic (pH < 4) and acidic hydrolysis is a threat. The spray tank dilution water requires treatment with an alkalising agent. Caustic soda, ammonia solution, lime, or another base should be added in line with label directions to increase the pH to a preferred level and preserve Acetamiprid. After alkaisation, retest the spray solution by adding a few mLs of VADER 225 VeripHy and only progress to spray solution preparation at full scale when a yellow colouring is exhibited.

Fill spray tank ¼ to ½ full of water. Start agitation (using mechanical or hydraulic means. NOT air agitation), add the required quantity of VADER 225 VeripHy and continue filling with water. Add non-ionic wetting agents as recommended previously. Continue agitation for several minutes prior to spraying to ensure thorough mixing.

APPLICATION

Cotton

Ground Application: Ensure thorough coverage of foliage. This will require a water volume of at least 50L/ha.

Aerial Application: Ensure thorough coverage of foliage. This will require a water volume of at least 20-30L/ha.

Potatoes

Apply by ground or aerial application methods in sufficient water to ensure thorough coverage of infested foliage.

COMPATABILITY

VADER 225 VeripHy is compatible with mepiquat chloride, thidiazuron (±diuron).

VeripHy Colour Indication

Acetamiprid is subject to alkaline hydrolysis once diluted as a spray solution, being the degradation of active ingredient content on reaction with water, at pH > 7.

Acetamiprid is also subject to hydrolysis in strongly acidic solution once diluted as a spray, being the degradation of active ingredient content on reaction with water, at pH < 4.

The magnitude of degradation of Acetamiprid varies with temperature, time held in the spray tank, the presence of other chemicals and contaminants and the extent to which the pH level is greater than 7, or lesser than 4.

To proactively manage the threat of hydrolysis, VADER 225 VeripHy is equipped with colour indication technology. This forewarns when there may be a problem and equally provides surety when there is not.

Add a few mLs of VADER 225 VeripHy to a sample of water to be used in the spray solution preparation and mix thoroughly.

If a yellow colouring is exhibited, this signals that the spray solution is weakly acidic to neural (4 < pH < 7) and hydrolysis is not a threat with no further action needed. Progress directly to spray solution preparation at full scale.
