What Insect Cuts the Blossoms off Tomato Plants?

Tomatoes are beloved by gardeners for their versatility and flavor, but they can be frustrating to grow. One common issue tomato growers face is the loss of blossoms or young fruit. Blossoms are necessary for tomato plants to produce fruit, so losing them can significantly impact a harvest. While several factors can lead to blossom loss, one culprit stands out: the tomato fruitworm.

Meet the Tomato Fruitworm

The tomato fruitworm, also known as the corn earworm, is a common pest that feeds on a wide range of plants, including tomatoes. The larval stage of the fruitworm is the most damaging because it feeds on the fruit and buds of tomato plants. The larva, which is usually green or tan with dark stripes, burrows into the bud and eats away at the developing blossom or young fruit. The damage caused by the fruitworm can be extensive, even resulting in total crop loss if left unchecked.

Identifying Tomato Fruitworm Damage

If you suspect fruitworm damage on your tomato plants, check for signs of burrowing or tunnelling in the blossoms or young fruit. The damage caused by the fruitworm is usually characterized by small holes or entry points in the fruit or buds. After the worm burrows into the blossom or fruit, it feeds on the insides, causing further damage. In severe cases, you may even find the worm itself in the damaged fruit.

Preventing Fruitworm Damage

Preventing fruitworm damage can be challenging, but there are several steps you can take to reduce the risk. One approach is to apply a pesticide specifically formulated to target fruitworms. There are various insecticides available in the market to choose from. Always read and follow the pesticide label instructions to ensure safe and effective use. Another method is to handpick any visible worms or eggs from plants. Be sure to dispose of them away from the garden or compost bin.

Another strategy to prevent fruitworm damage is to use preventive measures. Covering plants with lightweight row covers or protective netting can stop fruitworm moths from laying eggs on the plants. Regularly monitoring plants and checking for signs of damage, such as holes or entry points, can also help detect fruitworms before they cause too much damage.

Conclusion

The tomato fruitworm is a common pest that can cause substantial damage to tomato plants. Identifying the signs of fruitworm damage and taking preventive measures can reduce the risk of blossom loss and help ensure a more bountiful harvest. As always, the best approach to pest management is an integrated approach, combining different strategies to minimize the impact of pests on your garden.
