Efeito de adyuvantes na tenacidade de fungicidas cupricos em folhas de cafeeiros
The purpose of this report was to search among the so-called "adhesive despersers" or commercial adjuvants for those which best associate themselves with the cupric sources (copper oxychloride, cuprous oxide and copper hidroxide) thus furnishing larger tenacity in the interaction. The data obtained led to the following conclusionsÑ 1- Of the three sources used, all of which were formulated in water, the larger tenacity was obtained with cuprous oxide; 2- Regarding tenecity, the action of the adjuvants is specific. Within the sources utilized, the best associations were the following. 2.1 Cuprous oxide with the adjuvants Ortho-spray sticker and Haiten. 2.2- Copper oxychloride with the adjuvant Sandovit; 2.3- Copper hydroxide with the adjuvant Esapon; 3- Bordeaux mixture at 1.5 was the formulation with larger tenecity
