CONTROL OF VIRAL DAMAGES ON TOMATO IN OPEN FIELD, BY TREATMENTS WITH A PGPR STRAIN OF PSEUDOMONAS PUTIDA
Plant growth promoting rizhobacteria (PGPR) are able to promote growth of plants.
PGPR propriety is often associated with control of plant pathogens by induction of systemic resistance (ISR). Some PGPR strains increase yield and may induce plant resistance under field conditions providing, for example, effective suppression of bacterial speck and spot of tomato or to protect against TSWV. Some species of Pseudomonas have PGPR/ISR propriety.
In this work, results are illustrated about the use of a PGPR strain (C13) of Pseudomonas putida, on tomato cultivated in open field.
C13 strain suspensions were inoculated on tomato plants before transplanting and, one time per week for 9 weeks, on Perfect Peel tomato plants.
Inoculations of this PGPR strain were carried out in combination with increasing doses of nitrogen (0, 50, 100 and 150 kg ha-1). As expected, yield of tomato increased with nitrogen doses but, in combination with C13 inoculants, yield increased plus 9%. Statistically significant was the reduction of tomato fruits with viral symptoms, when C13 was inoculated, with respect to no inoculation (incidence 2.7 and 5.3%, respectively). In conclusion, results demonstrate that strain C13 of Pseudomonas putida is able to improve yield and to protect tomato against viruses in open field.
