摘要: | 荔枝生產會遭遇到許多重要的關鍵性害物,包括荔枝椿象、多種蛾類幼蟲、荔枝細蛾、東方果實蠅、荔枝炭疽病及荔枝露疫病等,本研究以24目與32目的網目搭配減少化學農藥防治次數,評估荔枝減藥生產果實對於病蟲害防治的效果。正常施藥組以每隔7-8天施藥1次進行防治,共施藥7次;網室減藥生產組進行化學防治方式施藥2次後覆網,網內再施藥1次,共施藥3次;另外以噴水作為不施藥對照組。本研究並未發現任何病害的發生,蟲害亦無發現東方果實蠅危害,但是皆有荔枝細蛾危害。目前荔枝害物的防治方式皆以化學藥劑防治為主。本研究將針對會威脅到荔枝生產的重要害物,根據這些害物發生生態以化學農藥搭配物理防治、精準施藥及搭配低風險植物保護資材等防治方式進行應用,達成荔枝生產農藥減量的生產管理方式。 Lychee production is often plagued by various important pests, including lychee stink bugs, various moth larvae, lychee fruit borer, oriental fruit fly, lychee anthracnose, and lychee downy mildew. This study evaluated the effect of reducing the use of chemical pesticides on pest control by using 24- and 32-mesh nets in lychee production. The normal pesticide application group was treated every 7-8 days for a total of 7 times, while the netting group applied chemical control twice before covering the nets, followed by one more application inside the net, for a total of 3 times. In addition, a control group was treated with water only. No diseases were found in this study, and there was no evidence of damage from the oriental fruit fly, but there was damage from the lychee fruit borer. Currently, chemical pesticides are the main method used to control lychee pests. This study will focus on the important pests that threaten lychee production and use a combination of chemical and physical control, precision pesticide application, and low-risk plant protection materials according to the ecology of these pests to achieve a pesticide-reduced production management system for lychee production. |
