1、 What medicine effect does root knot nematode use

1. How to distinguish: if the leaves of the plants on the ground are yellow and half dead, remove the plants from the pot in time, or dig away a little soil to expose the root system. If there are nodules on the root system, it is mostly root knot nematodes

2. Chemical control: root knot nematode can be infected and easy to relapse. It can be controlled with Ligen sand. Cut off all the root nodules and destroy them. Prepare liquen sand emulsion mixed with 1500 times water, dilute and soak the root system of the plant, and be careful not to soak on the leaves to avoid burning the leaves. After soaking, dry the root system of the plant, and prepare a pot soil for planting again. When putting on the pot, add 2 tablespoons of Ligen sand granules into the soil to prevent the recurrence of root knot nematodes

2、 How to prevent root knot nematode

1. Overhead flowerpot: Flower friends who raise flowers in the open air can pad the flowerpot and keep the bottom 5cm away from the ground to avoid rainwater carrying insect eggs from the bottom and infecting them through water and soil

2. Clean water quality: when watering flowers at ordinary times, ensure that the water quality is clean and avoid watering rainwater that has fallen on the ground

3. Regular pot change: when raising flowers at home, the pot soil should be changed regularly, such as once a year, which can not only prevent the occurrence of root knot nematodes, but also prevent soil hardening and nutrient loss

4. Medicament prevention: usually planting flowers and burying Ligen sand granules in the soil can also prevent the occurrence of root knot nematodes
