Other claims from this paper (14)
- Intervention effect Pre-sowing technical D.D.T. caused no tobacco phytotoxicity at 27 lb./acre.
- Intervention effect Technical D.D.T. at 75.6 lb./acre caused no phytotoxicity in three-week-old tobacco seedlings.
- Intervention effect Pre-sowing parathion at 1–8 lb. per acre had no harmful effect.
- Intervention effect Parathion at 22.7 lb./acre seriously stunted three-week-old tobacco seedlings and killed many.
- Intervention effect Pre-sowing toxaphene at 6‐4 lb. per acre did not injure tobacco seedlings.
- Intervention effect Parathion-treated beds showed no residual phytotoxicity on resowing four months later.
- Intervention effect Toxaphene-treated beds showed no residual phytotoxicity on resowing four months later.
- Intervention effect B.H.C. dust at 2–25 lb. per acre temporarily distorted and stunted young tobacco seedlings.
- Observation B.H.C. symptoms at up to 11 lb./acre were transitory.
- Intervention effect At 37.5 lb./acre B.H.C. killed many plants and severely stunted the rest.
- Association Resistance to B.H.C. phytotoxicity increased with tobacco plant age.
- Intervention effect Technical B.H.C. at 75.6 lb./acre caused considerable mortality in three-week-old tobacco seedlings.
- Intervention effect Beds resown four months after 6‐4 lb. technical B.H.C. per acre showed no visible phytotoxicity.
- Intervention effect Beds resown four months after 12.8 lb. technical B.H.C. per acre showed no visible phytotoxicity.
