1. Symptoms: root knot nematode is a major pest in the stage of succulent seedlings, which is hidden in the soil layer. In serious cases, it will cause many plants to shrink or rot.
2. Control method: the plant growth environment should be adjusted, and the temperature, light, ventilation and humidity should be increased appropriately. This will reduce the chance of it getting sick. In the early stage of the disease, low toxicity and low residual agents, such as 3% furantan granules, should be used for treatment.
1. Symptoms: this pest mainly adheres to the back of leaves and stems and sucks nutrients from roots, which is easy to find. It can move at a speed visible to the naked eye and is easy to infect. Adults will climb from one flowerpot to another, and should be cleaned up in time when they are found. Many white dots appeared on the injured plants.
2. Control methods: when there are few pests, the pests can be killed by hand toothpicks and needles. When there are many pests, they can also be treated by spraying 1000 times of 40% Omethoate or 1500 times of 50% malathion. Spray once every 7 days or so, generally 2-3 times after spraying, the condition will get better. When the pest is serious, take the plant out of the basin, cut off the rotten roots and clean the roots. After that, leave it in a ventilated place for 2-3 days. Wait for it to dry, and then transplant it to a new pot of soil for slow maintenance.
