Cutworms and related nocturnal larvae can cause serious damage to outdoor succulents because they feed at night and hide during the day.
Growers may notice missing tissue, chewed leaves, or sudden damage before they find the pest itself. Checking the soil surface and nearby hiding places is important.
Prevention and control depend on regular inspection, removing larvae when found, and keeping outdoor growing areas clean enough that pests are easier to spot.
治療藥劑
🧪 賽洛寧 (功力)
- 優點
針對有翅膀結構的害蟲特別有效果。 - 缺點
因為是乳劑狀態,所以用量要很精準,才不會產生藥害。
🧪 馬拉松 (治蠅寶)
- 優點
藥效持久,能持續提供植株保護,從土壤澆灌也能殺死幼蟲。 - 缺點
藥品名稱有「松」字的藥味都非常重,使用時要做好防護。
🧪 芬化利 (速滅精)
- 優點
藥性溫和,可與多種除蟲藥劑混合使用,效果加倍。 - 缺點
屬於低毒藥劑,但粉塵較輕,調藥時要慎防吸入,以免中毒。
🧪 塞速洛寧
- 優點
是塞速安、賽洛寧2種殺蟲劑的混合,能夠對抗的蟲害很廣泛,幾乎能想到的蟲類都包辦了,澆灌、葉噴都可以。 - 缺點
混合藥劑的單價較高,毒性也較單一藥劑稍微高一點,噴藥時必須做好防護,確實洗手戴好口罩,施作時也要特別留意風向。
