Disease control in pod bean (Phaseolus Vulgaris L.) with trichodermaasperellum, milk in natura and fungicides

The aimed of this work was to evaluate the effect of foliar application of milk in natura, Trichodermaasperellum and different fungicides in the control of angular leaf spot (Pseudocercosporagriseola), white mold (Sclerotiniasclerotiorum) and anthracnose (Colletotrichumlindemuthianum), in the cultivar of common beans low butter pod, in the field. The design used was a randomized block, with 7 treatments and 4 repetitions. The treatments used were: 1- witness, 2- weekly sprays of Trichodermaasperellum (2.0x106spores mL-1); 3- weekly sprays of 20% cow's milk; 4- weekly sprays of 20% milk, plus vegetable oil (1.6 mL L-1); 5- sprays of azoxystrobin (80 g a.i. ha-1); 6- sprays of mancozeb (2.0 kg a.i. ha-1) and 7- sprayings of diphenoconazole (0.3 L a.i. ha-1). Severity of anthracnose and white mold in pods and angular leaf spot on leaves and productivity were evaluated. With the severity data of C. lindemuthianum and P. griseola, the area under the disease progress curve (AUDPC) was calculated. Alternative products (T. asperellum and milk, with and without vegetable oil), reduced AUDPC from angular leaf spot and anthracnose, but less AUDPC was observed in treatments with mancozeb and diphenoconazole. There was no effect of treatments for the incidence of white mold, number and weight of pods.
