The behaviour of the Oana maize hybrid to the attack of pathogenic agents, by using chemically treated seed, at the Agricultural Research and Development Station of Podu-Iloaiei, Iaşi county

Abstract

The results of experimental investigations, conducted during 2001-2003 at the Agricultural Research and Development Station of Podu-Iloaiei, on the behavior of the Oana maize hybrid, treated with insectofungicides, for the prevention and diminution of the attack of pests and pathogens during plant sprouting and vegetation, have shown that the products used for seed treatment, before sowing, ensured a good plant germination, sprouting and development. The attack of Agriotes spp. was much diminished in the variants treated with insecticides (F%=0-0.6) and in the ones where insectofungicides were used (F%=0-0.7). At the fungicide-treated variant, the attack was greater (5.4%-7.4%). Under conditions of using insectofungicides, the attack of pathogenic agents (Drechslera turcica and Gibberella roseum) has registered the lowest values (F%=1.1, respectively, 2.4).
