General
The product is effective by contact and ingestion and has no systemic nor gas action. Ensure that adequate penetration of crop by spray mixture is obtained to achieve optimum results
particularly in tall and dense plant populations.
Mixing instructions
To obtain better emulsion stability it is recommended to first mix the concentrate with a small
amount of water (1 part to 5 parts of water) before adding to rest of the water.Compatibility
Can be used in combination with most insecticides and miticides normally used for sucking insects and mite control. The addition of sea weed extract (ile Seaborne) will not affect efficacy.
pk of the spray water
The efficacy of SUMI-ALPHA 200 EW may be reduced by very hard water (> 1000 p.p.m solutes) and by water with a high pH value.
When SUMI-ALPHA 200 EW is used, the optimal efficacy thereof will be obtained in water with a pH of 4,5 - 5,5. Water of a higher or lower pH than 4,5 - 5,5 should be buffered to pH 4,5 - 5,5 by using Curabuff (Reg. No. L 4731).
Where Curabuff is used to adjust the pH of the water the Curabuff must be mixed with the total volume of water required for that particular tank mixture before adding the SUMI-ALPHA 200 EW.Use the spray mixture without delay and do not allow to stand for prolonged periods.
Aerial application
Aerial application of SUMI-ALPHA 200 EW may only be done by a registered Aerial Application Operator using a correctly calibrated, registered aircraft according to the instructions of SABS Code 0118 (Aerial Application of Agricultural Pesticides). Ensure that the spray mixture is distributed evenly over the target area and that the loss of spray material during application is restricted to a minimum. It is therefore essential that the following criteria be met:
Volume: A spray mixture volume of 30 liters per hectare is recommended. As this product has not been evaluated at a reduced volume rate, the registration holder cannot guarantee
efficacy, or be held responsible for any adverse effects if this product is applied aerially at a lower volume rate than recommended above.
Droplet coverage: 30 to 40 droplets per cm? must be recovered at the target area.
Droplet size: A droplet spectrum with a VMD of 250 to 280 microns is recommended. Limit the production of fine droplets less than 150 microns (high drift and evaporation potential) to a minimum.
Flying height: Maintain the height of the spray boom at 3 to 4 meters above the target. Do not spray when aircraft dives, is in a climb or when banking
Use suitable atomising equipment that will produce the desired droplet size and coverage, but which will ensure the minimum loss of product. The spraying system must produce a droplet spectrum with the lowest possible Relative Span. Position all the atomisers within the inner 60 to 75 % of the wingspan to prevent droplets from
entering the wingtip vortices, The difference in temperature between the wet and dry bulb thermometers, of a whirling
hygrometer, should not exceed 8°C.- Stop spraying if the wind speed exceeds 15 km/h.
- Stop spraying under turbulent, unstable and dry conditions during the heat of the day.

- Handle with extreme care.
- Poisonous when swallowed, inhaled or absorbed through the skin.
- Extremely toxic to fish and bees.
- Fiammable - Do not store near open flame.
- Store away from food and feed and out of reach of children, uninformed persons and animals.
- Precautions
- Avoid inhalation of spray mist, oral intake and skin contact.
- Wear protective clothing during mixing and application.
- In case of skin contact, wash with soap and water.
- Do not eat, drink or smoke while applying or preparing the spray mix, or before washing face and hands.
- Prevent spray drift onto other crops, grazing, rivers and dams.
- Prevent contamination of food, feed, drinking water and eating utensils.
Invert empty container over the spray or mixing tank and allow to drain for at least 30 seconds after the flow has slowed down to a drip. Thereafter rinse the container three times with a volume of water equal to a minimum of 10 % of that of the container. Add the rinșings to the contents of the spray tank before destroying the container in the pre-scribed manner.
Destroy empty container by perforation and flattening and never re-use for any other purpose.- Resistance Warning
SUMI-ALPHA 200 EW is a group code 3C insecticide. Any insect population may contain individuals naturally resistant to SUMI-ALPHA 200 EW and other group code 3C insecticides.
The resistant individuals can eventually dominate the plant population if these insecticides are used repeatedly. These resistant insects may not be controlled by SUMI-ALPHA 200 EW or any other group code 3C insecticide.To delay insecticide resistance:
- Avoid exclusive repeated use of insecticides from the same insecticides group code. Alternate or tank mix with products from different insecticide group codes.
- Integrate the control methods (chemical, cultural, biological) into control programs.
Resistance of African bollworm (Helicoverpa armigera) to synthetic pyrethroids has been confirmed. Please refer to the RESISTANCE WARNING for more particulars.
All other crops: DO NOT apply more than two applications per growing season. If a pyrethroid gives poor performance DO NOT re-spray with any synthetic pyrethroid, even at a corrective dosage rate. Use a product with a different insecticide group code.
