Disease and Pest Control of Sugar Apple

anthrax

If the sugar apple is infected with anthracnose, adverse symptoms such as leaf fall and fruit blackening and rotting will appear. In order to prevent the disease in time, you can spray the sugar apple with a solution of carbendazim or thiophanate-methyl in appropriate proportions 1-2 times when the new shoots are growing and the fruits are setting after the flowers fall.

Root rot

When the sugar apple is not properly cared for, such as excessive watering, high temperature and humidity, or application of inappropriate fertilizers, its roots will be damaged and rot, and symptoms of root rot will appear. In order to prevent sugar apple from being attacked by this disease, in addition to taking more precautions in normal times, once diseased plants appear, they must be removed in time and sprinkled with appropriate amounts of lime and sulfur powder to effectively control the spread of the disease.

Stem rot

If the sugar apple is infected with anthracnose, symptoms such as seedling death, treetop withering and fruit rot will appear. In order to prevent the occurrence of this disease, similar to the prevention and control of anthracnose, you can spray the sugar apple 1-2 times with a solution of carbendazim or thiophanate-methyl prepared in an appropriate proportion when the new shoots are sprouting and the fruits are setting after the flowers fall.

Red Spider

Sugar apple is easily attacked by red spider mites. Therefore, once the density of red spider mites is found to be too high, pesticides should be sprayed promptly and comprehensively, such as the suspension of spiroclofonate.

Scale insects

In addition, sugar apples are susceptible to scale insects. To this end, in spring and autumn, when the new shoots of the sugar apple sprout and young fruits develop, spray cypermethrin solution for prevention and control.

In summary, this article discusses how sugar apple should deal with five common diseases and pests. I hope everyone can remember the key points and take appropriate countermeasures when necessary to prevent the rapid development of pests and diseases and endanger the normal growth and development of the sugar apple field.
