The problem will piobably last into June, Pepper said, since eggs wei e found in large numbers.

Two major concerns faced county farmers this week. What can he done about the present crop, and how can later cut tings he protected? Peppei lecommended imme diate harvesting of hadly in fested fields, if giowth is high, enough to warrant it, and spraying of the stubble two on three days after harvest. If the crop is a week away fiom desirable haivest time, the spiay can he applied and the crop harvested a week lat ei In no case should spiayed fields he haivested inside sev en days, he said. Peppei said any one of four materials can he used as stub ble spiay Guthion, 25 per cent emulsion, should be applied at two pints per acie.

Lueck said that of over 200 fields inspected over the last two weeks, only 20 treated last fall with heptachloi or diel dnn had weevil control, and those were fields where the spray was applied last fall for the first time. Pepper reminded farmers that ‘ absolutely no heptachlor or dieldun may be spiayed on hay fields this spring or sum mer.” ‘He also pointed out that stuibble spiay applied for 'wee vil control will not control leaf hoppers He i ecommended a spray of methoxychloi when the new growth is six inches high Non-Chemical Control Meanwhile, a ciash piogram on non-chemical methods of pest control was urged toy the National Agucultuial ißeseaich Advisoiy Committee in its quar terly lepoit to the U S.
