ABSTRACT The present research work aimed to determine the effect of three doses of potassium phosphite in the control of Phytophthora capsici in Capsicum annuum variety Papriking. 35day old plants were transplanted into 4-kg black polyethylene bags containing a sterile substrate composed of agricultural soil plus worm humus in a 2: 1 ratio. The treatments under study consisted of the application around the foot of the plant in the form of a potassium phosphite drench in doses of 5ml / l (T2), 7.5 ml / l (T3) and 10 ml / l (T4) plus a control alone with the pathogen (T1) and an absolute control (T0), with 8 repetitions. The distribution of the treatments was carried out using a completely randomized design. Fifteen days after transplantation, 20 ml was added per bag. of a suspension of P. capsici zoospores at a concentration of 4000 zoospores per milliliter. Immediately afterwards, 30 ml per bag of the product evaluated according to the dose corresponding to each treatment was applied, repeating the application twice more at intervals of 10 days. The three doses of potassium phosphite evaluated had a similar effect on the control of root rot. Treatment T3, which consisted in the application of 7.7 ml / l, presented a lower incidence (37.5%) of the disease, compared to the inoculated control treatment (T1), which presented an incidence of 87.5%.
