The common pests of water spinach mainly include liriomyza sativae, Spodoptera exigua and Pieris rapae.
There are many ways to deal with these pests. The best way is to set up insect nets and use 20 mesh insect nets, which can effectively control beet armyworm and cabbage caterpillar.
Setting insecticidal lamps in the field can also control Spodoptera exigua and Pieris rapae.
If there are pests such as liriomyza sativae during the growth of water spinach, low-residue pesticides such as cypermethrin can be sprayed for control. However, in order to prevent drug residues, no more drugs can be used when the harvest period is 10.
