When your situation is otherwise, you can use fairly mild chemicals like Bt (Bacillus thuringiensis) which is recommended by most experts. Truth be told, organic measures work best for small scale farmers and in situations where the infestation isn’t that bad. Whenever you see the eggs or larvae, you can simply handpick and destroy them in order to end their development circle. When laid, the eggs usually appear white, after which they turn brown right before they hatch. As mentioned earlier, the first thing that happens is that they lay eggs on the leaves, so it’s these that you should look out for so that you don’t give the larvae a chance to proceed to the fruit. It’s equally important to regularly check on the tomato plants because with that you can identify any sign of fruitworm infestation. Tilling during fall also exposes the worms to cold under which the fruitworm pupae cannot survive. With this, the worms are more exposed to the predators which will help get rid of the ones lying on the surfaces. There’s no better time to do so around the tomato plants than when fall knocks. However, it’s not about how to till, but when you till. Tilling around your crops comes with a number of advantages, and in this case, it’s considered to be effective when you want to get rid of fruitworms. Other parasitic options are: big-eyed bugs, minute pirate bugs and damsel bugs, but these are often attracted to stinging nettle, daisies, goldenrod and alfalfa, so you can also plant them alongside the tomatoes.
On the other hand, you can also buy the wasps and release them into your tomato garden.
It’s these that will in the end attract the parasitic predators like Trichogrammma wasps which feed on the worms. You can do this by going the natural way which involves planting dill, parsley and asters next to the tomato plants. Well, if you want something effortless, let predators deal with the worms on your behalf. You can go the organic way or opt for chemicals, so basically it’s all about what you prefer or what you have at hand. There are a number of ways you can use to destroy these worms on your tomatoes.
