Navel orange canker is a common plant fungal disease, which causes serious harm to the growth and quality of navel oranges. Next, we will introduce some specific methods to prevent and treat navel orange canker.
*Analyse. Navel orange canker is mainly caused by fungi, which mostly occurs in humid and warm environments, which makes the surface of orange peel ulcer, gangrene and other symptoms, and reduces the market value and eating quality of navel oranges.
Prevention and control methods. Biocontrol.
Use antagonistic bacteria: Choose effective antimicrobial sprays, such as Bacillus subtilis, which can effectively inhibit the growth of fungi.
Application of beneficial microorganisms: By applying beneficial microorganisms, such as red shell fungus, Trichoderma fastidiosa, etc., the number of fungi in the soil is reduced, and the possibility of disease occurrence is reduced.
Agronomic measures. Proper irrigation: Avoid over-irrigation, keep orange orchards well drained, and reduce the impact of humid conditions on diseases.
Pruning and dredging: Timely cleaning up fallen leaves and other debris in the orchard to maintain air circulation can help reduce the chance of disease.
Chemical control. Spraying fungicides: Preventive spraying with effective fungicides, especially in the early growth and disease-prone periods of navel oranges, can effectively control the occurrence and spread of diseases.
Rotate the use of biocides: Regularly change the use of biocides with different mechanisms to reduce the resistance of pathogens to biocides.
