The statement that is not true about plant diseases caused by bacteria is that most are controlled with bactericides. While bactericides can be useful in managing some bacterial diseases, they are not as widely applicable or effective as fungicides are for fungal diseases. The effectiveness of bactericides varies significantly depending on the specific bacterium causing the disease, and in many situations, they may not offer a reliable solution due to resistance or difficulty in achieving sufficient penetration into the plant tissue.

In contrast, the need for strict sanitation practices in managing bacterial diseases is well established, as bacteria can spread easily through contaminated tools, water, and surfaces. Additionally, the development of resistant plant varieties is a common strategy employed in plant disease management to enhance resilience against specific bacterial pathogens. Thus, while there are management strategies like sanitation and the use of resistant varieties, the reliance on bactericides is generally more limited compared to fungicides for fungal pathogens.
