Strewing pesticide 殺虫剤散布

2015.7.2
雨は朝遅くにやんだ。巻柏に殺虫剤を撒いた。月に一度の作業だ。去年酷くやられたのを決して忘れない。
The rain stopped late morning.  I strewed pesticide to protect my selaginellas from armyworms.  This is a monthly task.  I won't forget that they suffered terribly last year.

殺虫剤はよく効いているようだ。一つ心配なのはこの顆粒にしている成分だ。殺虫効果は一月位続くのだが、顆粒は溶けても無くならない。水はけが悪くらないかなぁ。
The pesticide has been working very well.  One thing I am worrying is the substances that forms its granular shape.  The effect last about a month, but the granules are melted and stay.  It may affect the drainage of the soil.
