How to tell if tomato plant has bacterial wilting?
The expression of bacterial wilting symptoms may vary depending on the crop.#N#In the early stages of the disease, the first visible symptoms of bacterial wilting are usually seen in the youngest leaves at the ends of the branches. At this point, only one or even half a leaf may wilt and the plants may appear to recover at night in colder temperatures.#N#As the disease develops rapidly under favourable conditions, the whole plant can quickly wilt and dry out although the dried leaves remain green.#N#In young tomato stems, for example, infected vascular bundles can appear as long, narrow, dark brown stripes. A collapse of the stem can also be observed in young, succulent plants of highly sensitive varieties.

How to control root node nematodes?
Try high beds to improve drainage and control root node nematodes that weaken plants and make them more prone to disease.
How do pathogens spread?
The pathogen is primarily spread through the soil and passes through wounds or natural openings into the roots. After an infection, the pathogens multiply and migrate upwards through the vascular system, where they finally block the water transport of the plant. This leads to withering, and usually the rapid death of the plant. The pathogen is released into the soil by infected plants, so that neighbouring plants can be infected via root contacts. It can also be introduced into the plants by pruning wounds. Contaminated water sources, symptom-free, but contaminated seedlings, as well as human contact or machines with infested soil remnants can also be ways for the BW to enter a clean field.
What is the little leaf of Brinjal?
Little Leaf of Brinjal: This is a serious viral disease of brin jal. The disease is transmitted by leaf hopper (Cestius (Hishimonus) phycitis and Amrasca biguttula biguttula). The leaves of the infected plants in the early stages are light yellow in colour. The leaves show a reduction in size and are malformed. Disease affected plant are generally shorter in stature bearing a large number of branches, roots and leaves than healthy plants. The petioles get shorter considerably, many buds appear in the axil of leaves and internodes get shortened thus giving the plants a bushy appearance. Flower parts are deformed leading the plants to be sterile. Infected plants do not bear any fruit. However, if any fruit is formed it becomes hard and tough and fails to mature.

The infected leaves show the presence of irregularly scattered necrotic pale yellow spots over the leaf lamina. Later on, these spots coalesce resulting in complete wilting of the leaves. The roots of the affected plants are split open longitudinally, a characteristic dark brown discoloration if the xylem vessels is observed.
