Title
Toxicity of Sprays and Spray Ingredients on Pear Psylla Nymphs
F. Z. Hartzell Journal of Economic Entomology 1930. doi:10.1093/jee/23.1.190
Other claims from this paper (7)
- Intervention effect All tested ingredients were toxic to pear psylla nymphs at the tested strengths.
- Association Pear psylla nymph mortality rose with the white oil proportion.
- Intervention effect Nicotine at 1-3200 was toxic to pear psylla, with only slight gain from higher doses.
- Intervention effect Ingredient mixtures had approximately additive destructiveness against pear psylla.
- Recommendation The authors indicate nicotine content can be reduced when other compatible toxic materials are added.
- Recommendation Pine oil and Hardwood neutral oil may materially reduce nicotine content in regular sprays.
- Intervention effect Penetrol in Bordeaux with reduced nicotine appeared safe to pear foliage in normal spring temperatures.
