    Thisrehearsalwascarriedout in thecanton Cumandá, county of Chimborazo, throwingthefollowingresults: thecombination of vegetable extractssamplethebestresultsbeinglocated in therange TO, headedbythetreatment E4D3 (I Summarizepepper-garlic-nettlecocktail + thedose of 400 ml. of solution) with a stocking of 1,91; followedbythetreatment E4D2 (I Summarizepepper-garlic-nettlecocktail + thedose of 300 ml. of solution) with a stocking of 1,96; in third place wefind to thetreatment E4D1 (I Summarizepepper-garlic-nettlecocktail + thedose of 200 ml. of solution) with a stocking of 2,13, leaving at theend to thewitness in a range AND with a stocking of 5,14. Wefindthattheextracts E4 (pepper + I age + nettle), E3 (Nettle + I Age) and E1 (Pepper + Nettle) theyoccupytherange TO withstockings of 2,00; 2,48 and 2,61 respectively, leavingthewitness in therange C with a stocking of 5,14, isalsoappreciatedthatthe doses D3 (400 ml), D2 (300 ml) and D1 (2,91) theyoccupytherange TO, withstockings of 2,56; 2,76 and 2,91 respectively, whatmeansthatamongdosedifferencesdon'texiststatisticallysignificant; butallthe doses overcomethewitnessthatoccupiestherange B with a stocking of 5,14. One can observe thatthetreatment E4D3 (Extract of pepper + I age + nettlewith 400 dose ml) itoccupiestherange TO with a stocking of 6,92%; in therange AB wefind to thetreatments E4D2 (Extract of pepper + I age + nettlewith 300 dose ml) and E4D1 (Extract of pepper + I age + nettlewith 200 dose ml) with 8,75% and 10,92% respectively; leaving in thelast place withtherange D to thewitness and E2D1 (pepper + I agewith 200 dose ml) withstockings of 28,56% and 31,25% respectively. Itisobservedthattheextract E4 (pepper + I age + nettle) itoccupiestherange TO with a stocking of 8,86 area% to foliateaffected; whiletherest of treatmentsoccupiestherange B, leaving in last place to thewitnesswith a stocking of 28,26 area% to foliateaffectedbytrips. One can observe thatthe doses D3 (400 ml) and D1 (200 ml) theyoccupytherange TO withstockings of 17,48% and 18,79% respectively; whilethewitnessoccupiestherange B in last place with a stocking of 28,56 area% to foliateaffectedbytrips. He/shealso stands out in therange TO thetreatments E4D2 (pepper + I age + ortiga/300 ml) and E4D3 (pepper + I age + ortiga/400 ml) with a stocking of 1% of fruitsaffectedbytripseachone; leaving in last place in therange B to thewitnesswith a stocking of 8% of fruitsaffectedbytrips. Theextract E4 (pepper + I age + nettle) and E3 (Nettle + I age) theyoccupytherange TO withstockings of 1,44% and 3,44% respectively; in therange AB wefind to theextracts E2 (pepper + I age) with a stocking of 4,42% and E1 (pepper + nettle) with a stocking of 4,78%; leaving in therange B to thewitnesswith a stocking of 8,00% of fruitsaffectedbytrips. Itisalsoappreciatedthatthe doses D3 (400 ml) and D2 (300 ml) they are in therange TO withstockings of 2,92% and 3,33% of fruitsaffectedrespectivelybytrips; leavingthewitness in therange B with a stocking of 8% of fruitsaffectedbytrips. Theextract E4 (pepper + I age + nettle) itislocated in therange TO with a stocking of 1,71 Kg. leaving in therange B to thewitnesswith a stocking of 0,30 Kg. One can observe thatthewitness has a betterrelationshipbenefit-cost, because in this he wasnotcarriedoutany variable investment, howeverthetreatmentswithextract E3 (nettle + I age) they are themost beneficial duringthe time of therehearsal and thefirst 4 crops.
