GENERAL INSTRUCTIONS

ACTIVIST 225 VeripHy is a soluble concentrate to be dissolved in water for spray application. ALWAYS add a non-ionic agricultural wetting agent at a rate of 0.025% of active material. This is 25 mL/100L for most wetting agents. It is most effective when spray schedules are initiated on young insects. The lower rates are used on small larvae and light infestations, the higher rates on larger larvae and heavy infestations.

MIXING Add a few mLs of ACTIVIST 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 acidic (pH < 7) and alkaline hydrolysis is not a threat with no further action needed. Progress directly to spray solution preparation at full scale.

• If a purple 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 Methomyl. After acidification, retest the dilution water by adding a few mLs of ACTIVIST 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 ACTIVIST 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 Proper timing and good coverage is essential for effective insect control.

Larvicidal: Apply at the recommended rates when the insects first appear and repeat as needed. Apply the lower rates on small caterpillars and light infestations of insects. Use the higher rates on larger caterpillars and heavier infestations. Best control is obtained when spray schedules are initiated on young insects.

Ovicidal/Larvicidal: Use these rates only where crops are regularly monitored for eggs and larvae. Use the lower rate when eggs are present. Use the higher rate when heavy egg lays occur and/or when first to second instar larvae are present (up to 5 mm long). If large larvae are present (longer than 5 mm), use the larvicide rates as recommended. This product may be used at ovicidal/larvicidal rates in conjunction with other recommended larvicides used to control other insects.

Ground Application Apply as a coarse spray with low pressure ground equipment. Use sufficient water to obtain thorough, uniform coverage.

Special instructions for Tree Crops/Vines Dilute Spraying

• Use a sprayer designed to apply high volumes of water up to the point of run-off and matched to the crop being sprayed.

• Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of run-off. Avoid excessive run-off.

• The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice.

• Add the amount of product specified in the Directions for Use table for each 100L of water. Spray to the point of run-off.

• The required dilute spray volume will change and the sprayer set-up and operation may also need to be changed, as the crop grows.

Concentrate Spraying

• Use a sprayer designed and set up for concentrate spraying (this is a sprayer which applies water volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.

• Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume.

• Determine an appropriate dilute spray volume (see Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.

• The mixing rate for concentrate spraying can then be calculated in the following way:

  1. Dilute spray volume as determined above: For example 1500L/ha.

  2. Your chosen concentrate spray volume: For example 500L/ha.

  3. The concentration factor in this example is 3X (i.e. 1500L ÷ 500L = 3).

  4. If the dilute label rate is 10g/100L, then the concentrate rate becomes 3 x 10, that is 30g/100L of concentrate spray.

• The chosen spray volume, amount of product per 100L of water, and the sprayer set-up and operation may need to be changed as the crop grows.

• For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Air Application For Cotton, Soybeans, Sorghum, Mung beans, Sunflowers, Pastures, Winter Cereals and Linseed only: DO NOT use less than 22L/ha water and increase the spray volume according to density of crop and pest pressure. Turn off spray boom while passing over creeks or dams.

COMPATIBILITY As the formulations of other manufacturers products are beyond the control of Imtrade, all mixtures should be tested prior to mixing commercial quantities.

VeripHy Colour Indication Methomyl 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. The magnitude of degradation of Methomyl 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. To proactively manage the threat of alkaline hydrolysis, ACTIVIST 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 ACTIVIST 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 acidic (pH < 7) and alkaline hydrolysis is not a threat with no further action needed. Progress directly to spray solution preparation at full scale. If a purple 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 Methomyl. After acidification, retest the dilution water by adding a few mLs of ACTIVIST 225 VeripHy and only progress to spray solution preparation at full scale when a yellow colouring is exhibited.
