General Instructions

 

Addition of Wetting Agent

When diluting with water, add a non-ionic surfactant at registered label rates.

 

Spray Preparation

Quarter to half fill spray tank with water. Start agitation (DO NOT use air agitation). Add the required amount of this product to the tank and complete filling with water. Add a non-ionic surfactant as recommended above. Continue agitation for several minutes prior to spraying to fully mix the chemical.

 

Application

 

a) Larvicidal:

Apply at the recommended rates when the infestation reaches an economically damaging level and repeat as needed. Apply the lower rates on small larvae and on light infestations of insects. Use the higher rate on large larvae and heavier infestations of insects. Best control is obtained when young insects are treated.

 

b) Ovicidal/Larvicidal:

Use these rates only where crops are regularly monitored for eggs and larvae. Use the lower rate when only eggs are present. Use the higher rate when heavy egg lays occur and/or when larvae are less than 3 mm long. If larvae are longer than 3 mm use the larvicidal rates. This product may be used at ovicidal/larvicidal rates in conjunction with other recommended larvicides used to control other insects.

 

Tree and Vine Crops - Dilute Spraying:

 

- Use a sprayer designed to apply high volumes of water up to the point of runoff 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 100 L 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.

 

Tree and Vine Crops - Concentrate Spraying:

 

- Use a sprayer designed and set up for concentrate spraying (that 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:

 

EXAMPLE ONLY:

 

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

 

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

 

3. The concentration factor in this example is: 3 X (ie: 1500 L / 500 L = 3)

 

4. If the dilute label rate is 100 g/100 L, then the concentrate rate becomes 3 x 100, that is, 300 g/100 L of concentrate spray.

 

- The chosen spray volume, amount of product per 100 L 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.

 

For concentrate application, use a spray volume of at least 200 litres per hectare.

 

For dilute application, apply to run-off. See Dilute Spraying above.

 

Non-tree and vine crops - Ground Application:

Apply as a fine spray preferably generated by cone nozzles. DO NOT apply as a fog or mist. For effective insect control, proper timing and good coverage are essential. Use sufficient water to obtain thorough uniform coverage. Use 100-400 L/ha spray mixture unless otherwise directed in the Directions for Use section.

 

Aerial Application

For ADZUKI BEANS, CANOLA, COTTON, LINSEED, LUCERNE, LUPINS, MUNG BEANS, PASTURE, PEANUTS, PEAS, SORGHUM, SOYBEANS, SUNFLOWERS, TOMATOES AND WINTER CEREALS:

 

Spray volumes:

For rates less than 1.5 L/ha: Dilute to any convenient volume no less than 1.5 L/ha.

 

For rates of 1.5 L/ha and higher: apply undiluted or diluted to give any convenient volume.

 

Droplet Sizes:

When applying at ULTRA LOW VOLUMES (ie: volumes less than 5 L/ha): use a spray of 80-120 microm VMD.

 

When applying at LOW VOLUMES (ie: volumes greater than 5 L/ha): use a fine spray (100-150 microm VMD).

 

To reduce drift and optimise results, avoid application in calm conditions and apply in light to moderate crosswinds.

 

Fungicide Resistance Warning

 

For insecticide resistance management, Cheminova Methomyl 225 Insecticide is a Group 1A Insecticide. Some naturally occurring insect biotypes resistant to Cheminova Methomyl 225 Insecticide and other Group 1A insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Cheminova Methomyl 225 Insecticide or other Group 1A insecticides are used repeatedly. The effectiveness of Cheminova Methomyl 225 Insecticide on resistant individuals could be significantly reduced. Since the occurrence of resistant individuals is diffi cult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of Cheminova Methomyl 225 Insecticide to control resistant insects. Cheminova Methomyl 225 Insecticide may be subject to specific resistance management strategies. For further information, contact your local supplier, Cheminova representative or local agriculture department agronomist.

 

Compatibility

Cheminova Methomyl 225 Insecticide is compatible with a wide range of pesticides in common use, eg: HALLMARK+ 10 ULV, Endosan+ 240 ULV, Thiodan+ ULV, Endosulfan ULV and Endosulfan ULV240.

 

Restraints

 

DO NOT use in covered or protected situations such as glasshouses, greenhouses or plastic tunnels.
