Citrus 2/2
Importance of the Use of a Wetting Agent -MeloCon®WP (10^11 spores/gram) for Control of Citrus Nematode
The spores of Paecilomyces lilacinus need to be applied to the root zone of the plants. A compatible wetting agent can promote the distribution of the spores in the soil, when it is drenched in with irrigation water. The spore distribution in different soil depths was demonstrated with and without a wetting agent.
Efficacy trial for MeloCon®WP repliecated in a lemon orchard in Somis, California
Trial Design: Randomized Complete Block
Replications: 4
Equipment: Sprinkler System
The effect of a wetting agent on the nematode population could be seen in a trial in a citrus orchard. The trial was started without an adjuvant for the first year. The adjuvant was used beginning with the second year of the trial.
Trial was set up in a mature lemon orchard with known nematode population. Three different rates of MeloCon®WP were compared with a reference product and an untreated control.
Trial was set up in a mature lemon orchard with known nematode population. Three different rates of MeloCon®WP were compared with a reference product and an untreated control.
Trial was replicated utilizing 4 trees per replicate per treatment for a total of 80 trees. MeloCon®WP was applied with a rate of 0.05, 0.1 and 0.2lb/1000ft (ca. 0.075, 0.15 and 0.29g/m²) . In 2007 and 2008 MeloCon®WP was applied twice a year. Applications were mixed and applied through standard spraying equipment utilizing a gas powered diaphragm pump system. Samples were collected from under each of the 4 trees replicates utilizing an auger to take the samples from the soil under the drip line to a depth of 12 inches. All samples were taken from the same general area under the tree.
