Gelatin capsules containing chloropicrin (Pic gel cap) were developed as a new formulation to reduce the potential human exposure risks associated with injection application methods. The objective of this study was to test the efficacy of a Pic gel cap formulation on soilborne pathogens and to determine the effects on strawberry plant growth and fruit yield. Three field experiments were conducted in strawberry greenhouses located in Mancheng County, China, in 2008-2010. The results demonstrated that effects of Pic gel cap on soilborne pathogens were similar to Pic injection; Pic gel cap effectively reduced key soilborne pathogens population, was partially effective against weeds, improved strawberry plant growth, and increased fruit yield significantly compared to the untreated control. Pic gel cap applied to preformed beds uses less fumigant than broadcast applications of Pic gel cap and can provide an equivalent level of disease control. The present study confirms that the Pic gel cap is a promising new formulation which provides field efficacy and marketable yields similar to Pic injection or methyl bromide in strawberry cultivation in China.
明胶胶囊含氯化苦 (Pic 凝胶帽) 作为一种新的配方开发，以减少与注射应用方法相关的潜在人类暴露风险。本研究的目的是测试 Pic 凝胶帽配方对土传病原菌的效果，并确定对草莓植物生长和果实产量的影响。2008-2010 年在中国满城草莓温室中进行了 3 次田间试验。结果表明，Pic 凝胶帽对土传病原菌的效果与 Pic 注射相似； Pic 凝胶帽有效降低关键土传病原菌种群，对杂草有一定防治效果，与未处理对照相比，草莓植物生长和果实产量显著增加。 Pic 凝胶帽预先应用于床，比广播应用 Pic 凝胶帽使用更少的熏蒸剂，并能提供同等水平的疾病控制。本研究证实，Pic 凝胶帽是一种有前途的新配方，在中国草莓种植中提供与 Pic 注射或甲基溴相似的田间效果和可销售产量。
