China and Russia co-operate on biopesticide research
Jul. 28, 2008
Jilin province, China, and the Russian Academy of Agricultural Science have achieved “positive” results in their joint research effort into the protection of vegetable crops against pests and diseases, says the Jilin provincial government’s Science and Technology Department. In the past few years, Jilin province has worked closely with Russia to develop biopesticides using aconitine extracted from the plant, Radix aconiti kusnezoffii.
Results of the large-scale testing of these products, published this July, revealed that the new biopesticides have reduced the required number of applications of chemical pesticides on crops. The new pesticides have also been effective in preventing aphid infestations and reduced damage caused by powdery mildew by as much as 67.5%
Jilin province has 670,000 ha of vegetable crops, of which 268,000 ha are routinely susceptible to crop diseases and pests, leading to an average 10-15% loss of produce per year. When crop disease is particularly virulent, worst hit areas can suffer losses of 50-80%. Authorities are increasingly turning to biological pesticides to try and combat chemical pesticide resistance and to reduce pesticide residues in crops, according to the Jilin Science and Technology Department. The vegetable crop protection project is part of a five-year series of agricultural science collaborations between the Department and the Russian Academy of Agricultural Science set to last until 2009.
