Jectarow ‐ A Commercial Unit for Applying Low Volumes of Toxicants to the Seed Furrow of Row Crops1

Jectarow was developed specifically to apply EDB at low volume into the cereal seed furrow for Heterodera avenae control. It has since been used successfully to apply a range of other toxicants. These include liquid formulations of the soil fumigants chloropicrin, and formalin, and emulsions of the fungicides quintozene and etradiazole and the insecticide chlorpyrifos. Suspensions of the powder formulations of captan and chlorothalonil have also been applied successfully using the microtube applicator. Other potential applications of Jectarow may include growth regulators, Rhizobium cultures, trace elements, fertilizers or nitrification inhibitors. Perhaps this machine offers the opportunity to inoculate antagonistic or competitive non‐pathogenic cultures into a required soil zone. Jectarow has the advantage that highly toxic compounds can be considered as being contained in a ≪ closed system ≫ Jectarow is a low cost machine that sells to the Australian farmer for $A 215–470 depending on the size of his cereal seed drill (16–120 rows). It is probable that in sophisticated agricultural systems several Jectarows could apply different toxicants on the same machine in the same crop simultaneously.
