Parasitic and Control Effects of Paecilomyces lilacinus against Aquilaria sinensis Root Knot Nematode in Hainan Province
摘要
Abstract
The parasitic effect of Paecilomyces lilacinus against Aquilaria sinensis (Lour) Gilg root knot nematode eggs was determined indoors with double temperature determination in Hainan province. The result showed that 91. 10% of the eggs were parasitized by the fungus at 18 days after inoculation with spore suspension of 3X107 spores/mL. The result of field experiment showed that Paecilomyces lilacinus solid inoculant could inhibit reproduction and harm of Aquilaria sinensis (Lour) Gilg root knot nematode, the bigger the agent dosage, the better the control effect. At 60 days after treated by the fungus solid culture at dose of 50 g/plant,the disease index was only 9, and the control effect reached 87. 50%. Meanwhile, the plant height of Aquilaria sinensis (Lour) Gilg increased by 32. 1% ,and the fresh weight of the above ground part increased by 46. 6%. The fungus solid inoculant showed a significant and lasting prevention effect on Aquilaria sinensis (Lour) Gilg root knot nematode disease. Paecilomyces lilacinus can not only inhibit parasitism and reproduction of Aquilaria sinensis (Lour) Gilg root knot nematode,but also promote the plant growth.关键词
