1. Aphids

Aphids are one of the most destructive pests on Earth, harming many plants, and monkshood is one of them. The damage caused by this pest is mainly that adults and nymphs suck the sap from leaves, stems, tender tips and tender ears, causing a large loss of nutrients from the plant and resulting in withering.

Control method: When dealing with this monkshood pest and disease, we can use 40% imidacloprid water-soluble concentrate 1500-2000x dilution to spray and kill them.

2. Red spider mites

Red spider mites are a pest that exists on many plants, and monkshood is no exception. This pest is very small in size and generally difficult to find. Its harmful method is to pierce its mouthparts into the leaves to suck sap, causing chlorophyll to be destroyed and resulting in yellowing. In severe cases, it can also cause leaves to fall off or even drop completely.

Control method: When dealing with this monkshood pest and disease, if only a few individual leaves are affected, we can remove them. If more leaves are affected, we can use 40% dimethoate EC 1500x dilution to spray the plant and eliminate this pest.

After the seedlings are affected, their ability to absorb nutrients and water will be affected, resulting in poor growth. In severe cases, it can also cause branches and leaves to wither. When the lesion encircles the stem completely, it will cause the entire plant to die.

Control method: When dealing with this monkshood pest and disease, we can use Juandun diluted 800-1000x or Fengqia Genbao 600-800x to drench the roots of the diseased plants. Generally, apply once every 10 days, and after 3 times it can be cured.
