Grafting Tomatoes for Production in the Hot-Wet Season
Tomatoes are difficult to grow during the hot-wet season. Flooding, waterlogged soils, diseases, and high temperatures can significantly reduce yields.
Grafting tomato scions onto selected rootstocks of eggplant and tomato can minimize problems caused by flooding and soil-borne diseases. Sometimes the use of grafted tomato plants can be the difference between harvesting a good crop and harvesting no crop at all.
Grafted tomatoes are more expensive than nongrafted tomatoes and should be grown only when there is a risk of either flooding, root-knot nematode, or soil-borne diseases such as bacterial wilt or fusarium wilt.
