Residual effect of glyphosate as a ripener on sugarcane.

R. A. Donaldson; N. G. Inman Bamber 1982

Other claims from this paper (5)

Intervention effect In one large trial with three successive sprayed crops, no residual effect of glyphosate on yield was found.
Intervention effect The residual activity of glyphosate was low in several trials under optimum moisture conditions.
Intervention effect Glyphosate increased sugarcane yields considerably through its ripening effect.
Intervention effect Glyphosate applied to the preceding crop reduced sugarcane yields by 11 to 17% in rainfed trials affected by drought.
Recommendation Glyphosate should be used only where cane is not stressed or likely to be stressed between spraying and harvesting.

Observation Root dry weight increased with plant age, with the maximum increase between 60 and 90 days after sowing.
Intervention effect Increasing salt concentrations significantly reduced the number of pods and the fresh and dry weight of pods per plant.
Intervention effect Salinity decreased grain yield and biological yield in both soybean genotypes.
Intervention effect PK 416 performed better than the other genotype under saline irrigation.

Observation Infected mother plants passed PMTV to only some progeny tubers.
Observation Symptomless plants produced only symptomless progeny in this cultivar.

Intervention effect Organo-mercurial fungicide greatly decreased PMTV establishment.
Intervention effect Fumigation with 2-aminobutane was ineffective.
Intervention effect Sulphur acidification greatly decreased infection by PMTV and S. subterranea.
Observation PMTV transmission resumed when treated soil pH rose.
Intervention effect Fungicides decreased infection of Nicotiana debneyi bait seedlings.
