咁如果我見到羅勒葉上面有一點點黃色，係有病定係有其他蟲呀？

好驚.........

肯定有虫! 嗯...應該系蚜虫

修剪晒有病害O既葉, 再用苦棟油啦, 有效快捷又方便, 不過一兩個星期唔好採集香草食用喎

苦楝油系用 "苦楝樹 NEEM" 既果實同種子製成既油


Neem oil
http://en.wikipedia.org/wiki/Neem_oil

Neem oil is a vegetable oil pressed from the fruits and seeds of the neem (Azadirachta indica), an evergreen tree which is endemic to the Indian subcontinent and has been introduced to many other areas in the tropics. It is the most important of the commercially available products of neem for organic farming and medicines.

Neem oil is generally red as blood, and has a rather strong odor that is said to combine the odours of peanut and garlic. It is composed mainly of triglycerides and contains many triterpenoid compounds, which are responsible for the bitter taste. It is hydrophobic in nature and in order to emulsify it in water for application purposes, it must be formulated with appropriate surfactants.

Azadirachtin is the most well known and studied triterpenoid in neem oil. The azadirachtin content of neem oil varies from 300ppm to over 2500ppm depending on the extraction technology and quality of the neem seeds crushed. Neem oil also contains steroids (campesterol, beta-sitosterol, stigmasterol).

有機農藥其中一種
因為果D細細隻成日O係葉底吸食汁液既蚜蟲仔真係好煩, 用過好多方法都唔得(應該係我冇咩時間成日噴), 所以用呢種一日噴一次既農藥, 效果非常地理想, 特別係對蚜蟲

咁我諗我真係要去搵下，因為呢期好多蚊滋仔，日日都要拎住枝煙水响度殺佢地，真係好煩﹗
咁係咪如果我要食嗰D香草，噴完一星期後先好食呢？

去花墟搵一定搵到呢隻油, 小心唔好俾人說o左去買咩"大滅虫"果d藥粉, 聲稱非常有效, 唔知點解我用就冇效...
其實如果唔趕住食咪等夠兩星期囉, 我試過用完苦油一星期後照食都冇事
