新园丁给的青骨菜心最近长势喜人，今天拿着盆兴冲冲得准备剪叶子了，结果一看，叶子上都是蚜虫..密密麻麻的，好恶心阿。。
是不是去买辣椒，熬水30分钟，然后冷了喷，就可以杀死？不过那么多菜，要用多少辣椒阿。。。

安慰一下, 现在蚜虫暴发, 我是看到就用手轻轻捏死, 多了就只能用药喷了
评论
蚜虫是一条条的吗？它应该会把叶子咬成很多洞。我那也有绿色的小虫，很小的。
评论
是黑色和绿色的，小小的，象小蚂蚁。。

跟我那一样。不要紧的，煮之前，拿盐水泡一下，全掉下来了。
评论
春天种菜就是有这样的问题. 安慰一下.
评论
用水冲就行了。蚜虫不是咬洞的，是吸汁的。
评论
谢谢。可是那些还没剪下来的菜怎么办呢？search了一下用烟灰不错。。等会要向有抽烟的同事“乞讨”了。
评论
谢谢，但水冲蚜虫到土壤里，蚜虫会死么？
评论
还是喷药效果好
评论
蔬菜喷药。。。就不算有机了吧。。
评论
密密麻麻的话，用辣椒水肯定不行！非药不可！
评论
大概会死的，反正爬不回来了。

天暖和了，头疼的问题就来了。

谢谢，那我先试试。

Aphid Control
Frequent Inspection. Catch them early. One "colonizer" can produce up to 80 offspring in as little as a week and is capable of doing so several times. Slowly walk through your garden several times a week paying close attention to the underside of leaves. Also check for aphids on newly purchased plants and transplants.
Don't over fertilize. Aphids prefer the new growth that is found in abundance in overly fertilized plants. Use only slow release fertilizers. It is also a good idea to grow plants inside or under a cover until they are large enough to be a little more tolerant.
Spray with water. A strong spray of water is an effective way to dislodge aphids from your plants. Most dislodged aphids will be unable to return to the plant. The Bug Blaster is a hose attachment that works great for this.
Home remedy for aphids. You can kill aphids by spraying, especially under the leaves, with a solution of 2 tsp mild dish or laundry soap to a bottle of luke warm water. The soap washes off the aphid's protective waxy coating and causes dehydration. You can also mix three parts luke warm water to one part vegetable or horticultural oil and a couple drops of dish soap. This mixture can be sprayed on to clog the respiratory spiracles of aphids. Spray once a week taking turns between solutions. If using these solutions on food plants, be sure to wash them before eating. If using the oil solution, don't spray on very hot and sunny days as the oil can magnify the sun and possibly harm the plant.
Prune away colonies. Aphids maintain the right to assemble. If you see a section of the plant containing aphids galore, snip it off and dispose of it. It doesn't cure the problem but it will slow the advance.

安慰一下, ，绿色，灰色和黑色我的青菜都有，我每天都要视察一轮我的菜地， 我一看到就用手狠狠地捏死它们

刚买了花椒，辣椒，收集了烟蒂。 明天分三块试验田，分别试验一下，看哪个效果最好。
评论
我家也是，好不容易种出几个红萝卜，几乎被蜗牛全部吃完了，郁闷。

同抱抱安慰。。

我家的菜地里也有，

我去年种的小白菜也长满了蚜虫,后来询问了万能的,有人说是种的太密了,水也浇的太勤了,LZ你就赶快间苗吃吧,采下来的用盐水泡泡就掉了,照样能吃,然后少浇水试试.
评论
留一颗专门喂蚜虫会不会有用
评论
效果都不好！
其实烟蒂应该不错，但澳洲烟太淡。我有自种的烟杆，泡水后杀蚜虫速效。绿色无污染！
评论
啊。。难道勤快也是个错。。
好的，我明天就剪着吃，看是它吃得快，还是我吃得快。。

能不能给你换点？ 在悉尼么？
