- Association April sowings had more aphid attack than May sowings.
- Observation June sowings mainly escaped aphid attack.
- Intervention effect Two to four demeton-methyl sprays controlled aphids effectively.
- Intervention effect A demeton-methyl spray followed by menazon controlled aphids effectively.
- Intervention effect Disulfoton top dressing controlled aphids, with slower initial action than sprays.
- Intervention effect Menazon top dressing controlled aphids, with slower initial action than sprays.
- Intervention effect Menazon granules below seed controlled aphids.
- Intervention effect Menazon granules below seed did not increase yield.
- Observation In 1962 first alatae appeared in mid-June.
- Intervention effect Early demeton-methyl and menazon sprays in 1962 were ineffective and gave poorer control than in other years.
