Effect of seed biopriming with Trichoderma harzianum strain INAT11 on Fusarium ear rot and Gibberella ear rot diseases
Fusarium ear rot (FER) and Gibberella ear rot (GER) are common fungal diseases of maize responsible for yield
losses and reduced kernel quality due to contamination by mycotoxins. Since no chemical treatments are
available to control Fusarium disease in maize, biological control could represent a promising sustainable
strategy. A commercial strain of Trichoderma harzianum (INAT11) was evaluated for its ability to antagonize
Fusarium verticillioides and Fusarium graminearum and to reduce disease symptoms in plants through induction of
a systemic resistance response in maize. Infection trials on maize plants under controlled greenhouse conditions
showed that INAT11 applied to seeds is capable of reducing both F. verticillioides and F. graminearum disease
incidence (37.1% and 30.7%, respectively) and severity (32.6% and 43.4%, respectively). Field trials performed
under natural infection conditions showed a reduction in deoxynivalenol contamination in kernels, while no
effect on fumonisin contamination was observed. The expression patterns of some defence-related genes belonging
to both the ISR (LOX10, AOS, HPL and OPR8) and SAR pathways (PAL and PR1) indicated the upregulation
of some ISR and SAR markers. These upregulations occurred at different levels likely related to the
lifestyle of these two fungal pathogens
Sex Pheromone Aerosol Emitters for Lobesia botrana Mating Disruption in Italian Vineyards
Despite the great amount of information on the European Grapevine Moth (EGVM), Lobesia botrana (Lepidoptera: Tortricidae), and the effective strategies available for its management, this moth remains the main key pest damaging grapevines in the Mediterranean and Central Europe wine-growing areas. Synthesizing and manipulating its sex pheromone components fostered the development of new dispensers to boost the effectiveness and sustainability of mating disruption (MD) programs. Recent MD research has highlighted that the effectiveness of aerosol emitters is comparable to that of passive dispensers when applied in large, uniform sites such as Spanish vineyards. However, aerosol emitters that are equally effective in geographical areas characterized by small-sized vineyards, typical of many Italian regions, have not received enough research attention. To face this challenge, herein the experimental aerosol emitter (product code: Isonet® L MISTERX843) was tested at three different application rates (i.e., 2, 3 and 4 units/ha) in three study sites, two in Tuscany (Central Italy in 2017 and 2018) and one in Emilia-Romagna (Northern Italy in 2017), respectively, for a total of five trials. To assess the efficacy of this novel MD aerosol emitter, three different application densities were compared with an untreated control and two grower’s standards. The latter were represented by passive (Isonet® L TT) and active (Checkmate® Puffer® LB) release dispensers, already on the market for EGVM MD and applied at, respectively, 200–300 and 2.5–4 units/ha. MD carried out with Isonet® L MISTERX843 led to zero catches of males in the pheromone traps. They also allowed for a significant reduction in the number of infested flower clusters and bunches, as well as in the number of nests per flowers cluster/bunch, if compared to the untreated control. As a general trend, MD effectiveness was fully comparable, or even better, if compared to the grower’s standard. In conclusion, our research pointed out that the Isonet® L MISTERX843 can allow for effective EGVM management in small-sized Italian vineyards. Lastly, our economic evaluation showed that the MD whole cost per hectare using active or passive release devices was comparable
Influence of environmental factors and plant protection products on the growth and survival of Trichoderma harzianum strain INAT11
Fusarium head blight of wheat (Fusarium graminearum, henceforth Fg) and Pink Ear Rot of maize (Fusarium verticillioides, henceforth Fv) are diseases caused by fungi of the genus Fusarium causing severe yield losses and mycotoxins contamination. In preliminary studies conducted by University of Padova (Italy), Trichoderma harzianum strain INAT11 (deposit number DSM25764) showed promising activity against Fg and Fv. Within the European research project BIOCOMES, it was therefore decided to investigate whether strain INAT11, applied as a seed treatment (i.e. below-ground), could actually control Fg and Fv in aerial plant parts (i.e. above-ground).
To evaluate whether seed treatments with strain INAT11 could constitute a feasible plant protection tool, the effects of environmental factors and conventional plant protection products, commonly applied in wheat and maize, on the growth of the antagonist were investigated
