标 题: ZT-花坛菜地杀虫杀杂草良方汇总(升级版)
发信站: BBS 未名空间站 (Wed Jun 4 19:55:33 2014, 美东)
本周末家坛活动,征集花坛菜地杀虫,杀杂草良方,偏方。感谢网友们积极参与,现汇
总如下。若还有新点子,请补充。
杀虫类
1. 玫瑰防蚜虫
玫瑰上喷洒大蒜水(一或两瓣大蒜,碾碎后加水250ML,过滤后喷在玫瑰上)。而最好的
方法是在玫瑰之间种上大蒜,蒜味能够赶走蚜虫。这个方法也可以用来防止真菌的感染
。种韭菜也防病.
2. 巧杀鼻涕虫
用浅盖里倒点啤酒,傍晚置于菜地、花坛地上,第二天早起收尸。
3. 洗碗剂兑水喷花,可防虫。
4. 往蚂蚁窝里到Backpulver(中文泡打粉?)。蚂蚁吃了,会肚涨而死。
5. 除虫菊素(pyrethrins)是一种源于菊科植物除虫菊的天然植物源杀虫活性物质,含
有六种杀虫活性成分,具有快速击杀害虫的特效功能,可广泛用于农林牧业生产和城市
园林防虫等领域。除虫菊素来源于自然,有天然的降解渠... 阅读全帖

这个Pyrethrum是从植物中提炼的,算是organic pesticide,对蚜虫,whitefly和

很多人相信有机蔬菜和非有机蔬菜有本质的不同,认为有机蔬菜比非有机蔬菜要健康。
实际上,有机蔬菜和用传统方式(施用农药和化肥)种植的非有机蔬菜没有多大区别。
有些情况下,有机蔬菜甚至比非有机蔬菜更不健康。譬如说,有机蔬菜可能含有更高的
致癌物质。
蔬菜和其他植物一样,在长期的进化过程中,形成了一整套对付害虫的办法,其中一个
有效的办法就是化学杀虫。所谓化学杀虫,就是在体内产生天然的杀虫剂。你来吃我,
我毒你一下。美国的科学家研究发现,常见蔬菜所有的器官和组织都含有微量的天然杀
虫剂。例如,大路货的卷心菜(cabbage)就含有49种天然杀虫剂及其代谢产物(1)。
不同蔬菜里天然杀虫剂的含量很不一样。含天然杀虫剂比较高的常见蔬菜和调味品有甘
蓝叶(collard greens),抱子甘蓝(Brussels sprouts),芥菜(brown mustard)
,山葵(horseradish),黑胡椒(black pepper),九层塔(basil),小茴香(

多年来一直被各种虫子困扰,pesticide 是不会用的,于是不断探索新法,对付黄瓜,
番茄比较有效的倒是最廉价的:1颗uncoated Aspirin 500mg + 2 gal 水+ 两勺Espon

每两周对叶子浇一次,用喷壶最好。

Products available to commercial pesticide applicators such as Pounce, Astro
and Onyx all show great promise in controlling this pest. Homeowners should
use outdoor tree and shrub insecticides containing imidacloprid or
bifenthrin. Homeowners should remove affected plants or plant parts and they
should be burned. The trunks of remaining plants should be treated with an
appropriate insecticide and monitored.
