Pest control of round-leaved arrowroot

Roundleaf arrowroot scale insect

The scale insects of round-leaf arrowroot are mainly mealybugs, which mostly occur on the back of leaves or the edges of leaves and rarely occur on the leaves. They absorb the juice from the leaves of plants by piercing and sucking, which seriously affects the healthy growth of the plants. In severe cases, it may even cause dead leaves and fallen leaves.

When attacked by scale insects, plants are very susceptible to virus infection. This organism has a strong reproductive capacity and can reproduce multiple times within a year. May every year is its peak season. Once it happens, it is more difficult to place it.

Prevention and treatment methods

For the prevention and control of scale insects, you can spray them with pesticides during the nymph stage. At this time, most of the scale insects have not yet hatched and their shells have not yet taken shape. They can be killed by using pesticides. Spray 1000 times of 40% omethoate every 7-10 days.

Roundleaf arrowroot spider mite

The damage caused by red spider mites to the round-leaved arrowroot is obvious. The spider is red or orange-yellow all over and has a sharp stylet, which it uses to absorb juice and other nutrients from the leaves, affecting the normal balanced metabolism of the plant and preventing it from developing normally. Red spider mites reproduce very quickly in a hot and dry environment and can cause serious damage.

Prevention and treatment methods

Keep the air normal, the environment uniform, and the humidity above 40%. Frequently spraying water on the leaves can prevent red spider mites from multiplying and becoming a disaster. You can use 1000 times the solution of 20% trichlorodicofol for spraying.
