1. 选育抗病品种

通常高种椰子比矮种椰子抗病,因此,在重病区应选种高种椰子。

2. 农业措施

1加强栽培管理

多施有机肥及人畜土杂肥。雨季及时开沟排除椰园积水,降低椰园湿度,干旱时及时浇水。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

2)铲除病株

巡查椰园,发现病植株及时铲除,将病组织深埋或集中烧毁,减少初侵染源;对处理过的伤口涂药保护。

3)合理间作

利用一些乔木下间种椰子,可大大减轻芽腐病的发生率,既可提高土地利用率,又可减少椰子树发生芽腐病死亡所造成的损失。

3. 化学防治

在每年10月到次年2月选用1 % 波尔多液,或58 % 瑞毒锰锌可湿性粉剂600倍液,或40 % 乙磷铝可湿性粉剂350倍液,或65 % 甲霜灵可湿性粉剂600 ~ 800倍液,或50 % 嘧菌酯悬浮剂3 000 ~ 4 000倍液,或250 g/L双炔酰菌胺悬浮剂1 000 ~ 1 500倍液,或69 % 烯酰吗啉锰锌可湿性粉剂800倍液,或50 %烯酰氟吗可湿性粉剂、或68 % 精甲霜锰锌水分散粒剂、或72.2 % 普力克水剂、或64 % 杀毒矾可湿性粉剂等药剂喷施植株心叶及幼嫩部分,减少初侵染源。每隔7 ~ 10 d喷药1次,连喷2 ~ 3次,可有效地防治此病。
