Bad weather in Veneto (IT): cracking on early varieties and Drosophila suzukii feared

Tech management

The start of the harvest, originally scheduled for May 20th, will be compromised by the impending losses due to prolonged rains and low temperatures for the season, while late varieties, with a delay in ripening, seem to have been saved for the moment.

Mode of action of Calcium in reducing macrocracking of sweet cherry fruit

Tech management

15 May 2024

The objective of the German study was to identify the physiological mechanism through which Ca reduces rain macrocracking (rain cracking) in sweet cherry fruit. Results demonstrate that multiple applications of CaCl2 were not effective in decreasing fruit macrocracking.

The use of fruit cuticle supplements as a prevention against cracking

The supplements help protect the fruit by preventing water absorption by coating the fruit with a hydrophobic layer. These supplements can also be used post-harvest to reduce doubling in the following growing season.

Putrescine makes trees more resistant to late frosts, while reducing the risk of cracking

The results showed that putrescine-treated buds decreased the overall malondialdehyde content (and thus the level of oxidative stress), while the rate of fruit set increased during most of the growing seasons evaluated.

Drosophila and cracking in cherry trees: optimistic forecasts from the Modena Phytosanitary Consortium

29 Dec 2023

Analysing D.suzukii monitoring data, an initial population level lower than the last three years was revealed, followed by a population increase in June that necessitated an intensification of insecticide interventions on late varieties.

CrackSense is the new project that hopes to solve the cracking problem

10 Aug 2023

The CrackSense project, coordinated by the research institute Volcani Center (Israel), was initiated in 2023. Its ambition is to better understand and predict the complex phenomenon of fruit cracking, a major agronomic problem, at the fruit, tree and plot level.

Applications of methyl jasmonate (MeJA) to reduce cracking

Crop protection

28 Jul 2023

The study conducted by the researchers of the Postharvest Research Group of Fruit and Vegetables (Orihuela, Spain) was to examine the effectiveness of preharvest methyl jasmonate (MeJA) treatments in reducing sweet cherry cracking during tree ripening and at harvest.

A research points to Calcium as a possible remedy against cracking

Crop protection

07 Jul 2023

Foliar applications of calcium salts (Ca) appear to reduce cracking, but the results available to date are still uncertain. First, the effects of Ca have been attributed to a decrease in osmotic potential, resulting in decreased water uptake.

Cracking: when it rains, it pours

Rain cracking is a serious physiopathy found in many fruits, especially cherries. Cracking causes enormous economic damage, both direct and indirect, and is set to become an increasingly important problem.
