520	3		_aIt was tested the sensibility in vitro for bencimidazolical fungicides on three Colletotrichum gloesporioides Penz. cultures and the biological effectiveness of the vegetable extracs proceeding from ten native plants of the Peninsula of Yucatan against a fungi culture. The experiment consisted on three bioenssays. At the first one, the sensibility from tour commercial fungicidas belonging to the bencimidazolical group (Prozycar 50 PH, Benlate PH, Tecto 60 and Cercobin M) were valued at different rates. The second one, corresponded to the impregnated extracts on filler paper disks from 0.6 cm inoculated with 2 mg from each e)dract, dissolved on Etanol at 10 and the third one consisted on adding the extracts added before to than medium culture in proportion to 2 mL -1 from mediun. The bencimidazolical fungicides Benlate and Prozycar were the best ones to control to C. gloesporioides Penz (micelial growing and sporulation density) since Benlate showed CEso and CE95 on micelial growing from 0.45994 and 0.68458 Mg mL-1 and 0.50149 and 0.73157 Mg mL-1 on sporulation, respectively. On the other hand the Prozycar showed 0.40354 and 0.61350 Mg mL -1 on micelial growing and the sporulation was 0.48729 and o. 71720 Mg mL -1. The results showed resistance with Tecto fungicide since it showed CEso and CE95 higher than 20 ppm. The stem vegetable extracts and the Catea urticifolia root are promissory to control C. gloesporioides Penz. Because of the lowest micelial growing rates 2.97 and 3.20 mm day-1 and effectiveness 47.77 and 43.66 per cent. In relation to density of sporulation the extrac with the lowest sporulation rates were: Theprosia cinerea leave with 17800 conidious mL -1and effectiveness 79.45 per cent; Acalypha gaumeri root with 115000 conidious mL -1; and effectiveness 86.72 per cent and Ageratum gaumeri leave with 549000 conidious mL -1 and effectiveness 36.61 per cent. during the first eight hours the vetable estracts inhibit to 100 per cent the germination of fungi conidious, although this process aborts beca use it supposes and fungistatical activity.
