Disease and Pest Control of Dianthus marinum

1. Rust

This is a very common pathogen that basically appears on the leaves of plants and sometimes on the stems of plants, forming small raised blisters. Generally speaking, its spores are brown or purple-black powder, appearing on the body of the sea pink and forming small blisters. Although the sea dianthus itself will not die after the onset of this disease and will still be alive, it will not live well. Not only will it become thin and weak, but it will also not grow, so we still need to be vigilant.

1. Physical prevention

Make sure the soil is loose to prevent water accumulation during planting. Pay attention to ventilation, clean the flower pots regularly, and apply fertilizer appropriately to prevent excessive nitrogen in the soil. If the planting area is relatively wide, you should be careful when choosing a site, and choose a relatively high place with good drainage.

2. Pathogen elimination

For plants that are already sick, immediate response should be taken. The sick plants should be removed as soon as possible, gathered together, and burned and destroyed to prevent the pathogens from continuing to spread and harming other branches.

3. Chemical control

In daily care, 63% of Mancozeb should be selected and prepared into a 600-fold solution for prevention and treatment. If the disease has already occurred, there are three types of pesticides that can be chosen to treat the plants, namely, fenadone, sodium carboxin and carboxin-ethyl, respectively.

2. Red spider

This is a common pest that often harms various types of plants. During the winter, they will lay eggs to ensure the survival of their offspring. After a winter, the eggs will begin to hatch in March. The incubation time varies, and it will generally not be fully hatched until April, causing harm.

1. Prevention and treatment

For red spider mites, you can use pesticides to eliminate them. In serious cases, you can use some special drugs to prepare a spray, or use cypermethrin emulsifiable concentrate for prevention and control. In addition, the use of mite-killing agent and cypermethrin emulsifiable concentrate can also achieve good prevention and control effects. In order to better prevent and control, new lipid membranes can be added to pesticides to enhance their effectiveness.
