  • Pakchoi, cucumber and cabbage were sprayed with 2% toosendanin EC, MEC or WP by using four different fan-shaped spray nozzles from a German company Lechler, ST110-03, ST110-04, ST110-05 and ST110-06, to analyze the relation between toosendanin depositon on three crops and nozzle size. The results show that the deposition of toosendanin EC and WP sprayed with droplet size between 151.7~215.3 on cucumber and cabbage leaves which had larger critical surface tension tended to increase in droplets size, but had no obvious difference between the treatments. Meanwhile the deposition of toosendanin ME on pakchoi and cucumber leaves gradually decreased with the increase of the nozzle sizes. The toosendanin deposition of the 3 preparations on the cabbage leaves decreased with increase in size of nozzles. It is suggested that nozzle ST110.03(151.7) be used to increase the deposition of toosendanin on the leaves of the tree crops.

Effects of Droplet Size on Deposition of Toosendanin on Three Crops

doi: 10.15886/j.cnki.rdswxb.2019.03.005

Abstract: Pakchoi, cucumber and cabbage were sprayed with 2% toosendanin EC, MEC or WP by using four different fan-shaped spray nozzles from a German company Lechler, ST110-03, ST110-04, ST110-05 and ST110-06, to analyze the relation between toosendanin depositon on three crops and nozzle size. The results show that the deposition of toosendanin EC and WP sprayed with droplet size between 151.7~215.3 on cucumber and cabbage leaves which had larger critical surface tension tended to increase in droplets size, but had no obvious difference between the treatments. Meanwhile the deposition of toosendanin ME on pakchoi and cucumber leaves gradually decreased with the increase of the nozzle sizes. The toosendanin deposition of the 3 preparations on the cabbage leaves decreased with increase in size of nozzles. It is suggested that nozzle ST110.03(151.7) be used to increase the deposition of toosendanin on the leaves of the tree crops.
