I Rust

This is a very common pathogen, which basically appears on the leaves of plants and sometimes on the stems of plants, forming raised blisters. Generally speaking, its spores are brown or purple black powder, which appear on the body of carnation and form small blisters. Although the sea carnation itself will not die and will live after the emergence of this disease, if it does not live well, it will not only be thin and weak, but also not grow, so it still needs to be vigilant

1. Physical prevention

Ensure that the soil is loose and prevent ponding during planting. Pay attention to ventilation, often clean the flowerpot and apply fertilizer reasonably to prevent excessive nitrogen in the soil. If the planting range is relatively wide, attention should be paid to selecting a relatively high place suitable for drainage

2. Pathogen clearance

For the sick plants, we should take immediate response, remove the sick plants at the first time, gather them, burn them uniformly and destroy them, so as to prevent the continuous spread of pathogens and harm other side branches

3. Chemical control

In daily nursing, 63% of mancozeb should be selected and prepared into 600 times solution for prevention and treatment. If the disease has occurred, there are three kinds of agents that can be selected, namely, Triadimefon, di rust sodium and Wei rust Ling, to treat the plant

II Starscream

This is a common pest that often endangers all kinds of plants. During overwintering, they will ensure the survival of their offspring by laying eggs. After a winter, the eggs will begin to hatch in March. The incubation time is long and short. Generally, they will not be fully hatched until April, causing harm

1. Prevention

For red spiders, pesticides can be used to eliminate them. In severe cases, some special drugs should be used to prepare sprays, or to use cap oil to prevent and cure them. In addition, good control effect can also be achieved by using mite dead net and aziridine EC. In order to better control, new lipid membrane can also be added to pesticides to increase efficiency
