Public demand for natural insecticides has lead researchers to develop a new organic pesticide , obtained from the giant knotweed plant. Pam G. Marrone , Ph.D. , presents her report at the 236th national meeting of the American Chemical Society , highlighting the development of the biopesticide that is safe to humans , animals and the environment. The product is expected to be available in October for conventional growing purposes , and in 2009 , a new formulation will be available to organic farmers.
The
giant knotweed grows along the East Coast and other areas , and is indigenous to Japan. The plant bloom from July to October , and can grow to over twelve feet tall. The scientists say the plant has the ability to innately fight diseases such as powdery mildew , and bacteria that invade fruits , vegetables and even garden ornamentals , as well as mold. The active compounds indigenous to the plant act as an alarm system , alerting plants to use their natural defenses.
Marja Koivunen , Ph.D. , director of research and development for Marrone Organic Innovations says the sale of synthetic pesticides is expected to diminish , and that biopesticide could account for 4.25% of sales , globally , by 2010. "I think it's a combination of the movement of green chemistry , trying to protect the environment and people's thoughts about their own health — maybe not even their health but their kids; and grandkids' health." "I think the time is right , there's more demand. People are becoming more aware of the negative effects of conventional pesticides. At the same time , growers are more willing to switch. They have more choices and incentive compared to 10 years ago , “says Koivunen.
The cost of buying organic is the subject of much discussion , and public concern about the health impact of synthetic pesticides has increased in recent years. Diseases related to organic pesticides include cancer and neurologic diseases , such as Parkinson’s disease , and infertility and birth defects. Organic produce without pesticide residues are shown to be higher in anti-oxidants , and simply taste better. The news is good.
