Root-knot nematode control is most effective with root sand. Once root-knot nematodes are found on a plant, all nodules on the root system should be cut off and destroyed. Prepare a mixture of 1500 times of Ligen sand emulsifiable concentrate and water, and dilute it well to soak the roots of the plants. Be careful not to soak the leaves to avoid burning them. After soaking, dry the plant roots and prepare a new pot of soil for planting. When potting, you can add 2 tablespoons of root sand granules into the soil to prevent the recurrence of root-knot nematodes.

1. How to identify: If you observe that the leaves of the plant on the ground are yellowing and half-dead, remove the plant from the pot in time, or remove a little soil to expose the root system. Come to think of it, if you find nodules on the roots, they are probably root-knot nematodes.

2. Chemical control: root-knot nematodes can be transmitted and easily Recurrence can be prevented and treated with root sand. Remove the lumps of soil attached to the root system, and cut off and destroy all nodules on the root system. Prepare a mixture of 1500 times of Ligen sand emulsifiable concentrate and water, and dilute it well to soak the roots of the plants. Be careful not to soak the leaves to avoid burning them.

2. Clean water quality: When watering flowers, make sure the water quality is clean and avoid watering rainwater that has fallen on the ground.

3. Change the pot regularly: When growing flowers at home, you should also change the pot soil regularly, such as once a year, which can not only prevent the occurrence of root-knot nematodes, but also prevent soil compaction and nutrient loss.

4. Chemical prevention: When growing flowers, burying root sand granules in the soil can also prevent the occurrence of root-knot nematodes.
