The continuous rain and low temperatures have presented significant challenges to the transplanting of Provençal Tomato. The transplanted seedlings are now enduring the harsh conditions. Growers must recognize that conventional nutrient management methods are no longer suitable for the current challenging climate and must adjust their strategies promptly to ensure normal growth and optimal yield for the tomatoes.

Continuous rainfall leads to excessively wet soil, reduced porosity, and root hypoxia, making root rot more likely. Simultaneously, lower soil temperatures further affect root development and function.

Prolonged rain also results in insufficient sunlight, inhibiting photosynthesis and slowing plant growth; under low-temperature and waterlogged conditions, even with sufficient soil nutrients, tomato roots struggle to absorb them effectively.

In this situation, the focus should be on improving the root environment and promoting nutrient absorption. During breaks in rain, the soil should be lightly hoeed to loosen it, enhancing soil aeration and increasing soil temperature. At the same time, irrigation should be controlled to avoid waterlogging; drainage ditches should be dug if necessary. Monband® GenMeng® can be used to stimulate new root growth.

Adjusting the nutrient program in a timely manner, improving the root environment, and enhancing plant resistance are essential to minimizing the adverse effects of bad weather and ensuring the yield and quality of tomatoes.
