It is understood that there are mainly 4 kinds of pests on snapdragons: thrips, whiteflies, aphids and red spider mites. Once discovered, flower lovers should pay attention. The symptoms and solutions of snapdragon pests are as follows:

1. Thrips

This pest is not common, but it is one of the pests that harm the growth of snapdragons. It parasitizes snapdragons as adults or larvae, feeding on young buds, tender leaves, flowers and young fruits. The symptoms of thrips damage are: tender leaves curl after being fed upon, and buds and flowers wither after being damaged.

Solution: When the above symptoms are found, flower lovers should pay attention. Look carefully, and once this pest is confirmed, immediately spray with 25% derris or 40% dimethoate 400-500 times dilution.

2. Whiteflies

Whiteflies are small white insects that are difficult to distinguish with the naked eye. The larvae mainly attach to the backs of snapdragon leaves, piercing and sucking sap, causing leaves to curl and dry up; adults harm tender leaves, sucking the sap from the leaf tissue.

Solution: When the above symptoms are found, flower lovers can spray with a 0.01% decis solution, or spray 40% omethoate, once every 7 days, spraying 3-4 times continuously.

3. Aphids

Aphids are one of the main pests harming snapdragons. They mainly attack the backs of snapdragon leaves, sucking the sap of young leaves and buds. The symptoms of damage by this pest are: leaves become wrinkled, withered and yellow, and even fall off.

Solution: Buy a sticky insect trap from the market and use it to catch them; in addition, flower lovers can spray with omethoate 1:150 dilution, and 1-2 times is enough to cure it. When there are many aphids, it is recommended to slowly pour this solution once to eliminate future trouble.

4. Red Spider Mites

This pest is difficult to distinguish with the naked eye in the early stage of infestation. It often hides on the backs of branches and leaves or in places with dense foliage, piercing and sucking the sap of leaves, buds and flowers, affecting normal growth and development. It not only affects the appearance, but in severe cases can even cause the whole plant to die.

Solution: When this pest is found, netting it off and catching it manually is relatively easy. In addition, flower lovers can use 20% dicofol emulsion, add 800-1000 times water to make a solution and spray it. This pesticide has a good killing effect on adults, nymphs and eggs.

(2) Snapdragon Disease Symptoms and Solutions

What to do when snapdragons get pests - after reading the above content, everyone should know! However, besides being attacked by insects, diseases also constantly endanger snapdragons. The main diseases of snapdragon are 4 kinds: downy mildew, powdery mildew, gray mold and root rot. The specific symptoms and solutions are as follows:

1. Downy Mildew

This disease easily occurs in cold and humid environments and is one of the main diseases of snapdragons. It mainly causes stunted growth of snapdragon seedlings, yellowing and downward curling of leaves. The symptoms are: a layer of gray fuzzy powder appears on the backs of snapdragon leaves.

Solution: When the disease is mild, disinfect the soil, heat the greenhouse and improve ventilation; when the situation is severe, it is basically over, just wait for the snapdragon to die!

2. Powdery Mildew

This disease is one of the main diseases of snapdragons. It mainly harms the stems, leaves and flower buds of snapdragons. Symptoms: a layer of white powder appears on the leaf surface. In severe cases, the leaves gradually wilt, with fewer and smaller flowers.

Solution: When the above symptoms are found, flower lovers should immediately spray chemicals, choosing 2500 times dilution of triadimefon or other suitable chemicals, spraying once every 10 days, and 2-3 consecutive sprays can cure this disease.

3. Root Rot

This disease can be said to be the most common disease of snapdragons, often occurring in hot summers. The cause may be root rot caused by flower lovers watering too much. Mild infection may not destroy the whole plant, but it weakens growth, causing branches of uneven length, thin and weak flower stems, and short and poor flower spikes.

Solution: After discovering this disease, promptly drench the root soil with 300 times dilution of amobam solution. At the same time, pay attention to timely ventilation and cooling, water appropriately, and ensure the potting soil is moist but not waterlogged.

4. Gray Mold

This disease mainly affects the stems and flowers of snapdragons. Symptoms: yellow-brown lesions surround the entire stem, causing the upper part of the plant to wilt. In severe cases, a large number of gray or light brown spores appear on the flowers and infected parts.

Solution: After discovering the above symptoms, flower lovers should immediately remove them, otherwise the disease will spread. In addition, spray with 65% zineb wettable powder 500-800 times dilution, once every ten days, and 2-3 sprays are enough.
