Identification and Control Methods for 11 Common Pests of Flowers and Plants in Spring

Right now spring is in the air and all things are reviving, a great period for the growth of potted flowers and plants. All kinds of flowers and plants begin to sprout and resume growth, and this season is also a peak period for the growth of various pests. If prevention and control are not carried out promptly, potted flowers and bonsai, as well as foliage plants that show the most obvious symptoms, will be infected with pests and diseases, which will pose a huge threat to the growth and survival of the flowers. When flowers and plants suffer pest damage, do you know what pest or disease it is? And what are the pest and disease control methods? Below, Huacaole shares with you the identification and control methods for 11 common pests and diseases of flowers and plants in spring.

Identification of 11 Common Pests of Flowers and Plants in Spring and Their Control Methods

I. Control of 11 Pests and Diseases of Flowers and Plants

1. Scale insects

There are many kinds of scale insects, covered with a waxy hard shell, round or oval in shape; the former is about 3-3.5 mm in diameter, and the latter is about 2 mm long and 1 mm wide. When few in number, they parasitize near the areoles of the plant or on the underside of leaves and inside leaf sheaths; when numerous, they parasitize everywhere on stems, branches, and leaves, sucking plant nutrients. The affected varieties are mostly Cactaceae, Euphorbiaceae, Liliaceae, Aizoaceae, and jade-type succulents. Scale insects reproduce quickly; each adult lays nearly a hundred eggs at a time, twice a year. The eggs are powdery, and after drying and cracking they drift with the wind, spreading onto the stems and leaves of plants everywhere.

Treatment method: When the number of insects is small, use a brush or bamboo slice to remove them manually or cut off the affected branches and leaves and burn them in a concentrated manner. When there are many insects, use 1 part cigarette butts and 1 part cigarette ash, add 40-50 parts water, soak for 1 day, mash and filter, then spray; this has a certain effect on newly hatched scale insects. Or purchase carbendazim and spray it.

2. Snails

Snails are divided into two types: those with shells and those without shells. They hide by day and come out at night, mostly hiding in moist, dark places during the day and only coming out at night to forage. They not only gnaw on young branches and tender leaves, but do not spare even old stems and leaves.

Treatment method: Clear away weeds, garbage, bricks and tiles and other debris around the potted plants, and purchase special effective agents for killing snails, such as Namei Tuoer, Nameike, slugicide, etc., and spray them.

3. Red spider mites

Red spider mites are about 0.5 mm in diameter, crawl fast, and are small in size, so they are not easy to find. They often gather in groups and gnaw on the epidermal tissue of stems and leaves, causing the affected areas to appear mottled and rough, in an unsightly white or yellow color. Red spider mites reproduce quickly in dry periods, and spraying water on leaf surfaces has an inhibitory effect on the damage. Among the affected flowers, Cactaceae, Aizoaceae genera, Euphorbiaceae genera, Liliaceae, etc. are relatively common.

Treatment method: You can make your own chili pepper water and spray it to kill them.
