回国两周回来发现梨树结果了，但是细看好像不是很健康。有个别叶子也长得不是很好，树干上也有些白毛毛。有的小梨仔上面有小疙瘩，或者像霉一样的白毛毛。但切开了两个来看里面又（还）没有虫。。
有经验的各位看这是不是长虫了？现在结了果就不能杀虫了，还有什么其他方法呢？
a fungal disease called pear scab
Neem oil might help to control this disease

我家也有一米一样的梨树但是不如你的粗壮
这喷喷药就好了，我家花园里的也得过
已经结了果了还能上药吗？
能喷药
梨树在英国长这么大需要多少年？结的果子质量数量如何？
我也不清楚呢，是之前的房主种下的。去年结了大概有50个果吧，没有外面卖的好看
