Organic Controls for Tomatoes


Tomatoes are attacked by a number of insects and diseases. Handpick tomato hornworms or spray with Bacillus thuringiensis (Bt). Control white flies and aphids by spraying insecticidal soap on the leaves.  For foliar diseases, such as early and late blight, select disease-tolerant varieties, clean up old crop debris in fall, rotate crops, mulch, remove infected leaves as soon as they are noticed, and spray with Serenade Garden Disease Control  (active ingedient is Bacillus subtilis) to prevent the disease from spreading.

 

Physiological problems such as cracking, sunscald, and blossom end rot can be avoided by keeping the soil consistently moist, planting tolerant varieties, and protecting plants from extreme hot and cold temperatures
