Response of cotton plant to seed coating with gaucho or cruiser and the efficiency of these treatments on sucking pests population [electronic resource].

Includes reference.

Two field experiments were carried out at El-Gemmeiza Agricultural Research Station, El- Gharbia Governorate, Egypt, during 2010 and 2011 seasons to evaluate the efficiency of two systematic insecticides i.e Gaucho and Cruiser as seed coating before sowing at two rates against pests which attack cotton during seedling period ( from emergence until 60 days old ) as compared with untreated seed treatment (control), in addition to some physiological aspects (growth attributes, earliness, seed cotton yield, components and fiber quality) of the Egyptian cotton ( Gossypium barbadense, L.), Giza 86 cultivar. The obtained results could be summarized as follow: 1-Applying systematic pesticides i.e. Gaucho and Cruiser as seed coating significantly increased leaf chlorophyll a, b and total chlorophyll contents, leaf area /plant, total dry weight /plant at 60 and 75 days old in both seasons and plant height at harvest and number of fruiting branches /plant in one season only compared with the control (untreated seeds wijh Gaucho or Cruiser). 2-Also, the two systematic pesticides significantly increased number of open bolls / plant, seed index, earliness % and seed cotton yieldl fed. in both seasons and boll weight in one season only as compared with the untreated control. 3-The tested treatments gave insignificant effect on micronaire reading and Pressley index in both seasons.
