Row Crop Disease Update – Kemerait
Planting time is critical for both seeding disease control and nematode control.
Have been asked several times about rate of azoxystrobin (e.g., Abound) in-furrow on twin-row peanuts. For lower-risk, 3 fl oz under each twin. For higher risk 6 fl oz under each twin.
Use of Aglogic on cotton- 5 lb/A is standard nematode rate, 6 lb is more robust and 7 lb/A is top rate and while biggest “punch”, may affect seedling vigor a little.
Fusarium Wilt in Watermelons
This disease is popping up which is no surprise as we already know we have it. Also we’ve found symptoms (in Cook Co) that are consistent with race 3 – pollinators are dying. Those plants are being tested now. Here is some good basic info on this disease put together by Turner Co Extension Agent Will Gay.
5 Unshakable Facts of Fusarium Wilt of Watermelon
- Fusarium Wilt of Watermelon (FON) will NOT infect any other crop other than watermelon alone.
- FON is soil borne and can persist for up to 16 years or more in some studies.
- FON prefers air temperatures of 77-80 Degrees F. Activity decreases at temperatures above the ones mentioned.
- There are 4 races of FON (0-3). Seedless varieties do not have resistance past Race 1. Seed varieties (pollinators) do not have resistance past Race 2.
3 Tips for Controlling Fusarium Wilt of Watermelon
- Currently proline at transplant is the only recommendation we have and there is sufficient data that suggest it be used in any situation where melon rotation is tight or FON has occurred in the past.
- UGA is currently researching chloropicrin for control of FON.
- Rotation and planting date will can also affect incidence, however, these may not be a viable option in some cases.
Our UGA specialists have put together an updated publication on “Fusarium Wilt of Watermelon in Georgia.”
