Controlling Measures of Bamboo Shoot Borer

Abstract

Controlling measures of bamboo shoot borer (Cyrtotrachelus sp.) were conducted at bamboo plantation plot at Royal Agricultural Station Pang Da, Samoeng District, Chiang Mai Province during October 2004 to September 2005. Randomized complete block design (RCBD) with 5 treatments and 5 replications were applied. The treatments comprised of applications of Chlorpyrifos at the rate of 75 ml per 20 litre of water, wood vinegar at the rate of 100 ml per 1 litre of water, green fungi (Metarhizium anisopliae), thinning and natural control. The results revealed that the major cause of bamboo shoot death was bamboo shoot borer (Cyrtotrachelus sp.) which affected bamboo deterioration and death at an average of 39.77 % and 48.86%, respectively. In addition, the treatment using Chlorpyrifos and wood vinegar showed the minimal percentage of mortality rate of 17.99 and 28.98, respectively. Furthermore, the result of statistic analysis showed that the natural control as well as application of Chlorpyrifos and wood vinegar were significantly different at p<0.05. On the other hand, the natural control and applications of thinning and green fungi were not significantly different. Thus, the effective controlling measures are the utilization of Chlorpyrifos and wood vinegar.
