From
17-18 Nov., 2012, Botanical Pesticide Industrial Technology Alliance 2012 was
held in Southwest
University
According
to the Institute for the Control of Agrochemicals, Ministry of Agriculture
(ICAMA), no scopoletin products have obtained the registration in China
For
a long time, the control of phytophagous mites mainly depended on chemical acaricides, so the resistance of mites has become more and
more serious. At the same time, overuse of chemical pesticides has destroyed
the ecological environment.
Chemical
acaricides are harmful to the environment and have a negative impact on
important natural enemies. They take a long time to decompose as they are
complex synthetic compounds that don't exist in nature. Therefore, extracts
from living creatures have great advantages over synthesized chemicals in
relation to the environment.
The
Plant Protection College of Southwest University discovered that mite feeding
is selective, and many plants contain a natural active ingredient to resist
mite feeding. So these plants can be developed into acarcides. And there are
resource advantages and broad prospects in researching and developing botanical
acaricides.
According
to a study on 40 herbs, Artemisia annua L. and turmeric have high potential for
development. At present, acaricides using Artemisia annua L. as raw materials
include 5% Artemisia annua L. ME, 0.5% scopoletin ME and 10% scopoletin•amitraz
SC.
In
summary, biological acaricides have great potential. They have many advantages
over agrichemicals, but are limited by their intrinsic defects. These defects
manifest in the following respects.
Firstly,
the activity of the active ingredients is not stable. They are secondary plant
metabolites, vulnerable changes of the environmental conditions (for example
temperature, humidity, illumination, the pH value of the soil, nutrition of the
soil and ecosystem, etc.), so therefore their stability is poor. Furthermore, the
source of Artemisia annua L. is limited geographically, which causes
difficulties in production.
