Diseases and Pests of Flame Tree and Their Control

Diseases and their control of flame tree

Damping-off

The disease mainly occurs when there is heavy rainfall in spring, and both seedlings and mature plants will be harmed. Symptoms include dark brown spots on the affected area, and in severe cases, large areas of death.

Prevention and treatment methods

Discover and remove diseased plants in a timely manner to reduce pollution sources and prevent the spread of diseases.

The soil needs to be disinfected before transplanting. You can mix 70% pentachloronitrophenol with fine soil in a ratio of about 1:30 and sprinkle it on the soil of the seedbed. When transplanting with new disease-free soil, you must use fully decomposed fertilizer and not fresh farm manure.

For spring-planted seedlings, spray 1000 times diluted 75% Benomyl or 1000 times diluted 70% Thiophanate-methyl about a week later, and then spray every ten days or so, alternating between the two.

Prevention and treatment methods

For the prevention and control of aphids, you can spray 3-5 degrees Baume lime sulfur mixture or 5% diesel emulsion before germination to kill overwintering adults and eggs. The second spraying can be done after the flowers fall, and the third spraying is done in autumn.

The larvae of cutworms and beetles are underground pests, so their prevention and control requires strengthened management, and do not apply uncomposted organic fertilizers. Tillage work is required in winter to dig the overwintering larvae out of the ground and freeze them to death. In addition, apply 3% Furadan granules at a dosage of 2 kg per mu into the soil at a depth of 10-20 cm through trenches.

For the larvae of geometrid moth and noctuid armyworm, 1500 times diluted 50% methamidophos can be sprayed.
