Reduction of Oil Spotting in Mandarins

Reduction of Oil Spotting in Mandarins

Through Research Programs in collaboration with Universities and Research Institutes in Greece and Abroad, it is proven that the superior quality and integrated innovative technologies of Agrology’s Functional Crop Nutrition® products, make a difference in crops from the very first applications!

Our goal is to demonstrate that application programs with Agrology’s Functional Crop Nutrition® products are an obvious investment for producers, as the financial benefits exceed the cost of supplemental applications!

One such Research Program on Mandarins var. Encore  was carried out in Chania in collaboration with Dr. Vasileios Ziogas, Researcher at Hellenic Agricultural Organization-DIMITRA (ELGO-DIMITRA).

The field was divided into two equal plots, one was used as the Control, while Agrology’s Program was applied to the other plot. In both plots, the farmer used the same plant protection and plant nutrition-fertilization program, apart from the additional applications with Agrology’s Functional Crop Nutrition® products, in this case Gravital® Force SC, aiming to reduce oil spotting in mandarins.

Oil spotting, also known as “Oleocellosis” or “green spotting,” is a physiological disorder in citrus fruits caused by the rupture of oil glands in the peel. This condition results in the appearance of small, dark green or brown spots on the fruit’s surface, which can be unsightly and reduce the marketability of the fruit.

Identity of the Experiment

Cultivation Season: 2018

Location: Ayia Pref. of Chania

Cultivation: Mandarin

Variety: Encore

Trees: Fully productive – Excellent nutritional status

Experiment Goals

The Objective of this Experiment for mandarin was as follows:

  • Reduction of Oil Spotting in Mandarins

Agrology’s Functional Crop Nutrition® Program

In the experiment Agrology’s Functional Crop Nutrition® product, Gravital® Force SC, was used.

Gravital® Force SC is a Bioavailable elemental Silicon and Calcium Biostimulant in liquid form, with a high percentage of available orthosilicic acid [35% Calcium (CaO) & 35% Silicon (SiO2)].

  • Enhances total yield and improves quality.
  • Promotes the absorption and utilization of nutrients such as Nitrogen, Phosphorus, Potassium, Iron, Zinc, and Magnesium.
  • Strengthens tolerance against both biotic and abiotic stress
  • Prevents the occurrence of physiological diseases

Treatments:

1) Control

2) Gravital® Force SC: 3 applications

  • 02/07/2018
  • 09/08/2018
  • 28/08/2018

Results

Reduction by 35% of Oil Spotting Index

  • Control: Oil Spotting Index = 2.77
  • Gravital® Force SC: Oil Spotting Index = 1.8
