The common underground pests of tomato have maggots, cockroaches, etc., and vegetable farmers should pay attention to prevention and control measures.

The larvae of earthworms live in the earth for a lifetime and like to sow seeds and seedlings that have just been sown. The prevention and control method for earthworms is to dip the vegetable fields in late autumn. Adults and larvae can be turned to the surface to freeze them, dry them, or be preyed by natural enemies and mechanically killed. Apply adequately cooked organic fertilizer, covered with plastic film, and stuffy, high temperatures kill pests in fertilizers. Avoid using unripe organic fertilizers. Before applying the fertilizer, sieve the earthworms out of the organic fertilizers so as not to attract adult eggs and bring larvae into the vegetable fields. In adulthood, the use of chafer's phototaxis, artificial capture or black light trapping.

Adult nymphs and nymphs bite the seeds and shoots that have just been sown in the soil, or they snap the roots and stems of the seedlings to make the seedlings die and the roots of the victims become numb. The earthworms in the underground activities strung the topsoil into many tunnels, which made it possible for the roots of the seedlings to ventilate and separate the soil. As a result, the seedlings were killed due to water loss, and the seedlings monopolized, resulting in a significant reduction in the yield of tomatoes. Controlling cockroach can use poison bait to trap and kill, soak 5kg of bean cake or wheat bran, then use 90% crystal trichlorfon 150g add water to bait mix tide, use l.5-2.5kg bait per acre, sprinkle in the ground or bed , killing and killing. Or use 1 to 5 kg of 50% phoxim per acre, mix 15-30 kg of dry fine soil and mix well and spread it into the vegetable field or open the ditch to the soil.
