Occurrence and control measures for Scelod ontalezoisii Baly in Nanning
摘要
Abstract
[Objective]In order to provide references for effectively controlling Scelod ontalezoisii Baly on grape,improving grape quality,and guaranteeing healthy development of grape industry in Nanning,occurrence regularity of Scelod ontalezoisii Baly was observed and chemical control test was conducted. [Method]Occurrence time and characteristics,damaged position,and regularity of Scelod ontalezoisii Baly was recorded; seven chemicals viz.,80% dichlorvos EC,2.5% cyhalothrin EC,5% fenvalerate EC,50% phoxim EC,48% chlorpyrifos EC,90% dipterex and 2.5% cyhalothrin EC were used for controlling Scelod ontalezoisii Baly in China-ASEAN Demonstration Park for Modem Agriculture of Nanning City from 2009 to 2011. [Result]Scelod ontalezoisii Baly occurred one generation per year,and mostly damaged grape young leaves,tender shoots,and pedicels from March to June. Overwintering adults of the insect mainly dispersed in soil of 5 cm depth with radius of 15 cm in the rhizosphere. Earth covering and plastic film mulching before imago coming out of the soil may reduce its harm to grape. Control efficacy of 50% phoxim EC and 48% chlorpyrifos EC reached 100%,2.5% cyhalothrin EC of 3000 folds and 5% fenvalerate EC showed the control efficacy of above 90%,and the control efficacy of 80% dichlorvos EC,90% dipterex and 2.5% cyhalothrin EC were 79.3-87.1%. [Conclusion]Taking measures,such as labor hunting imagoes and larvas,earth covering,and plastic film mulching,before imago unearth and spraying chemicals (50% phoxim EC,48% chlorpyrifos EC,2.5% cyhalothrin EC or 5% fenvalerate EC) in blade extension period could all effectively alleviate and control the harm of Scelod ontalezoisii Baly to grape.关键词
