菜粉蝶蝴蝶

这些轻浮的小蝴蝶可能会破坏紧张的芸苔属植物。
在油菜之间播种莳萝籽可以阻止这些害虫,因为莳萝的香气会混淆它们。如果你在芸苔属植物周围看到这些蝴蝶,把包装好的面包上的塑料夹子固定在一些叶子的边缘,作为害虫的威慑。看起来好像害虫已经在那些植物上下蛋了。蝴蝶用白色夹子,卷心菜蛾用米色夹子。
如果你的植物被攻击了,压碎任何绿色毛虫或把它们喂给鸡。它们经常隐藏在叶子的肋骨中部,使它们很难被发现。每天检查一下新下的CWB卵(明亮的黄色点,通常在叶子的背面),刷掉它们。也检查一下新孵化的幼虫,这些幼虫看起来像隐藏在叶子下面的绿色细线,看起来像叶脉。

白色菜粉蝶或甘蓝夜蛾攻击是一个标志,无论是:
你的植物需要更多的水。花椰菜需要彻底的,有规律的浇水,而不是每天喷洒。覆盖床可以减少水分流失,并促进水分在土壤中的水平流动。
2)在准备铺床的时候,你对完整的肥料有点吝啬。油菜喜欢腐殖质丰富的土壤,以提供良好的肥料供应。如果它们生长不稳定,可以在地膜下施用堆肥,或者像茶叶一样施用全肥,来解决这个问题。或者,他们缺少一些必要的微量元素,你可以通过喝一两杯高质量的海藻提取物茶(如阿卡迪亚茶、纳特拉克茶或海贝)来提供这些元素。
3)你已经添加了足够的肥料,但是土壤太酸或太碱,植物无法吸收它们抵抗虫害所需的养分。如果是太酸的情况-这可以通过使用白云石或农业石灰补救。如果你怀疑是酸性的,那就在每平方米的床上撒一把,然后浇水。避免在含有植物的床上使用熟石灰,因为它会燃烧植物的根。如果土壤的碱性太强,添加单质硫会降低碱度。
但是,如果他们把你的植物弄得一团糟,在等待土壤条件改善的同时,使用Dipel。Dipel可以杀死毛毛虫而不杀死好昆虫。

  1. Thank you for this advice as just yesterday I noticed my little brassicas looking a little under the weather and I applied some seaweed tea as I had read in your book that healthy plants resist disease and reading this article assures me I applied the right first aid and gives me further advice as to what I can do if they don’t recover properly Your book is fantastic and I actually found this site while googling it to see if I couldn’t suggest that you re-print it with further moon planting dates as I have recommended it to so many – and you’d already done it!!
    谢谢你的赞美,杰基。

  2. 嗨只是一个问题
    I think everyone will hate that we have “saved” some cabbage moth caterpillars, or rather my daughter has (she’s only 3 and absolutely loves the very hungry caterpillar book and adores the caterpillars she has saved from grandmas garden ( she was squishing them and this terrified my daughter, and the sweet sole she is, she had to save them) my question is though as stupid as it sounds as butterflies are the ones who lay the eggs but is it at all possible that a caterpillar could lay eggs as the caterpillars my daughter are in a container with tiny holes in the lid and I mean tiny tiny I made them with a red hot pin they havent been outside since she saved them they get their sun from the inside windowsill they have plent of food ant there is a bit of poop in the bottom of the container but on the underside of the lid there are now what look like tiny yellow cotton candies stuck to the lid with 2 of the caterpillars that have spent the past day on the underside of the lid one is staying quite close the eggs (they are definitely eggs) and the other has started to make a cacoon. This has confused me quite alot because the container has not got butterflys in it only caterpillars but all of a sudden there is eggs in the container
