| description |
Chili wilting or drying is one of the main diseases that causes very considerable losses in the production of the chili crop. The use of chemical fungicides is a common practice promoting resistance and environmental contamination. The reconversion of agriculture demands sustainable alternatives, among which the use of rhizospheric fungi = arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (Rpcv) stand out, which are seen as a valuable tool for the protection of crops. horticultural when they are applied through consortia. The general objective of the present investigation consisted in evaluating consortiums of mycorrhizal fungi and rhizobacteria as biological control vs Phythopthora capsici, in cultivars of 23 genotypes of chili peppers, from various agricultural locations in the Mexico country, were evaluated. The AMF that made up the consortium were: six strains of Rhizophagus intraradices with the codes Zac-19, Ced-20, Tab-21, Mér-22, Pap-23 and Jal-24. Likewise, four strains of rhizobacteria were included (Rpcv = Plant growth-promoting rhizobacteria), three of the genus Pseudomonas corresponding to P. lini, P. fluorescens, Acinetobacter guillouiae and one of the genus-species Aeromona caviae. The study treatments were four: T1 = Control (No nutritional contribution (water)), T2 = Consortium = (mixture) of the six AMF, T3 = Consortium of six AMF plus the consortium of four Rpcv, T4 = Chemical fertilization based on a nutrient solution. In the resistance of plants to the attack of P. capsici, They reduced the attack of the fungus P. capsici, in plants of 23 cultivars of chile; The Pasilla-type and Guajillo-type chili cultivars presented the highest resistance to the attack of P. capsici, when they were inoculated with AMF + Rpcv, while the Serrano, Puya and Jalapeño-type chilies were the ones with the highest susceptibility to the attack of the phytopathogenic fungus |

El uso de fungicidas químicos es una práctica común promoviendo resistencia y contaminación ambiental. La reconversión de la agricultura, demanda alternativas sustentables entre los que destacan el uso de hongos rizosféricos =hongos micorrízicos arbusculares (HMA) y las rizobacterias promotoras del crecimiento vegetal (Rpcv), los cuales se advierten como una valiosa herramienta para la protección de los cultivos hortícolas cuando éstos son aplicados mediante consorcios. El objetivo general de la presente investigación consistió en evaluar consorcios de hongos micorrízicos y rizobacterias como control biológico vs Phythopthora capsici, en cultivares de chile (Capsicum annuum L.). Se evaluaron 23 genotipos de chiles, procedentes de diversas localidades agrícolas en el país. Los HMA que conformaron el consorcio fueron: seis cepas de Rhizophagus intrarradices con las claves Zac-19, Ced-20, Tab-21, Mér-22, Pap-23 y Jal-24. Asimismo, se incluyeron cuatro cepas de rizobacterias (Rpcv = Rizobacterias promotoras del crecimiento vegetal), tres del género Pseudomonas que corresponden a P. lini, P. fluorescens, Acinetobacter guillouiae y una del género-especie Aeromona caviae. Los tratamientos de estudio fueron cuatro: T1= Testigo (Sin aporte nutrimental (agua)), T2= Consorcio = (mezcla) de los seis HMA, T3= Consorcio de seis HMA más el consorcio de cuatro Rpcv, T4= Fertilización química a base una solución nutrimental. En la resistencia de plantas al ataque de P. capsici, redujeron el ataque del hongo P. capsici, en plantas de 23 cultivares de chile; los cultivares de chiles tipo Pasilla y tipo Guajillo, presentaron la mayor resistencia al ataque de P. capsici, cuando fueron inoculados con HMA+Rpcv, mientras que los chiles tipo Serrano, Puya y Jalapeño, fueron los de mayor susceptibilidad al ataque del hongo fitopatógeno.
