![Bacterial wilt symptoms on potato plants. The first visible symptom on foliage is a wilting of the leaves at the ends of the branches during the heat of the day with recovery at night. As the disease develops, a streaky brown discoloration of the stem may be observed on stems 2.5 cm or more above the soil line, and the leaves develop a bronze tint. (c) A.A.

preventive control:
Preventive control 1. Remove and destroy all infected plants immediately
2.
2. Control nematodes
3.
3. Rotate crops other than solanaceous crops. Rice, corn, beans, cabbage and sugarcane are found to be resistant to bacterial wilt. Wilt severity in tomato was reduced by a rotation system using maize, okra, cowpea or resistant tomato.
4. tomato.
4. Since the bacteria can be transmitted through farm tools, wash or expose them to heat before using in another field
5.
5. For banana, remove and chop the plants surrounding the infected mat or within the radius of 6 meters from the infected plant to prevent further spread of the disease.
Notes for REVIEW
mh 18.6.09 pls check like in other datasheets, pestmodules, host list, specific recipes and structure. Black nightshade was mentioned in the text of hosts, African nightshade is one of our crops but was not mentioned in the header (and has no pestmodule), have included it, pls attach pest-module if possible.
