Cucumbers cultivated in greenhouse are often affected by different fungal diseases, the most commons are caused by two different pathogenic agents: Pseudoperonospora cubiensis (causing downy mildew) and Sphaerotheca fuliginea (causing powdery mildew). The trials carried out by Jose Morera S.L. have proved the efficacy of the mix between Blaster and Glass-Mg in order to control this kind of fungal disease.

Phytophthora infestans is an oomycete that causes the serious potato disease known as late blight or potato blighty, it also can infect tomato and some other members of Solanaceae causing seriuos damages all over the world. In this trial we used the mix of two different products Blaster and Glass-Mg to control and prevent the development of the disease, always tring to respect the environment using products with no chemical residues. On the other hand we also tested the product beneActiv, a bioestimulator that increases plant productivity and also improves potatoes quality.

In order to evaluate Bullet (P2O5 7%, K2O 14%, SL), a trial was established on a commercial orange grove, variety Navelate, with the principal objective to determinate the efficacy and selectivity of this product for the control of the fruit set on orange tree. The effectiveness of this treatment was compared with a reference product containing giberellic acid (16 g/L, SL). The test was carried out in a Navelate orange grove placed in a typical commercial area in Canals (Valencia). The experimental design was RCB (Randomized complete blocks) with a total of 4 reps of 60 m2/plot and 3 trees/plot per thesis. Two application timing were defined to increase the fruit set: majority of petals fallen and the beginning of fruit abscission (20 days later). The product effect on the fruit set was evaluated counting the number of flowers on four marked branches per plot and the number of fruitlets on the same marked branches. In this way it was possible to estimate the percentage of fruit set. The yield, the average weight per fruit and the number of fruit per tree was also evaluated. The number of flower and fruitlets was evaluated in order to estimate the percentage of fruit set; the studied variables were also the yield (Kg/tree), the average weight per fruit (g/fruit) and the number of fruits per tree. Results showed that Bullet increased the percentage of fruit set on marked branches (obtaining 16,34% of fruit set), more than untreated control (14,41%) and also more than reference product, which produced 11,58% of fruit setting. The yield using Bullet was 48 Kg/tree higher than in untreated plots and 12 Kg higher than using giberellic acid. Regarding fruit weight, plants treated with Bullet produced fruit with an average weight of 188 g/fruit, while plants treated with reference product (giberellic acid) produced fruits smaller with a average weight of 160 g/fruit.
