it is called a botanical pesticide
the pesticides in the plant wouldn't be excreted out of the plant although it had rained afterwards.. this is because, the chemical substances in the pesticide was diffused via the roots of the plant since the chemical substances are more concentrated than the fluid in the plant... Thus, the chemical substance are hypertonic to the plant roots... the substances from the roots will be transported through the xylem tissue of the plant until it reaches the leaves... so the pesticide is contained in the plant... the insect eats the plant and will eventually die afterwards... therefore, the rain couldn't easily wash out the pesticide.... :)
