MIXING

Half fill the spray tank with clean water and start agitation. Pour in the required amount of Perfekthion. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing.

EFFECT OF WEATHER
Best results will be obtained when the crop is growing vigorously. Systemic activity is reduced when crops are suffering from the effects of drought or under stress.
During hot weather conditions spray in the early morning and evening for best results.

HARVEST INTERVAL
Please see Table 1 for harvest interval or latest timing.

WARNING
Strains of the peach ‑ potato aphid (Myzus persicae) resistant to some organophosphorus insecticides have developed in certain sugar beet growing areas. Some populations of other aphid species and red spider mites are also now resistant to organophosphorus compounds. In these cases Perfekthion is unlikely to give satisfactory control.

IMPORTANT NOTES
Avoid spray drift onto neighbouring crops.
Do not apply Perfekthion to any crops suffering from stress or likely to suffer from stress in the immediate future, particularly if this is due to water deficit, frost or herbicide damage.
Do not apply Perfekthion if rain or frost is expected, nor if the crop is wet.
Wash equipment thoroughly after use.

SYMPTOMS OF POISONING
These may include excessive sweating, headache, weakness, faintness and giddiness, nausea, stomach pain, vomiting, small pupils, blurred vision; muscle twitching.
In cases of poisoning, reference must be made to the label where details of first aid and other medical data are available.

FIRST AID
If ANY of the above symptoms occur, particularly if there is known contamination.
