distributed chiefly by striped cucumber beetles. Destroy the beetles or drive them away by thorough spraying with bordeaux, 5-5-50. Gather and destroy all wilted leaves and plants. The most that can be expected is that the loss may be slightly reduced.
Downy mildew is a serious fungous disease of the cucumber known among growers as "the blight." The leaves become mottled with yellow, show dead spots, and then dry up. Spray with bordeaux, 5-5-50. Begin spraying when the plants begin to run, and repeat every 10 to 14 days throughout the season.
