Control Tomato Bacterial Diseases Before You See Them

摘要

Barterial spot, bacterial speck, and bacterial canker of tomato appear regularly in Michigan. Each disease can affect plant productivity, reduce yield, and/ or cause fruit disorders. Disease management issimilar for all three diseases. First, tomato transplants must be disease-free. This may be accomplished by using disease-free seed grown under a strict sanitation regime in the greenhouse. Bacterial speck is probably one of the easiest bacterial diseases to identify. Small dark-brown spots occur on the leaves with each spot surrounded by a yellow "halo." Typically just a few plants within a flat show symptoms initially. Although bacterial speck may not produce the panic that the other bacterial diseases do, speck can result in significant yield losses if the blossoms become infected.
