Fruit Logistica 2019, Messe Berlin

Fruit Logistica 2019, Messe Berlin

FRUIT LOGISTICA is the largest international fruit and vegetable fair in Europe held in Berlin. This year, more than 3,400 exhibitors from 84 countries took part at the fair, and the number of visitors from year to year is increasing, so this year the fair counted 78,000 visitors from 120 countries.

FRUIT LOGISTICA covers every single sector of the fresh produce business and provides a complete picture of the latest innovations, products and services at every link in the international supply chain. It thus offers superb networking and contact opportunities to the key decision-makers in every sector of the industry.

Representatives from Fresh Agriculture Technologies were there and they have presented MapMyApple application to big apple producers from different countries, such as France, Poland, Italy, Serbia, Macedonia, Turkey and New Zealand.

In the discussion apple farmers showed big interest in usage of this kind of application because as they say “all the data can’t be held in notebooks and they need a good application that can gather all the data together and give precise information in every place and at every time of the day.”

They all agreed about one thing ”farmers are aware that a lot of things have changed in the last few years, from the weather conditions, to soil composition and market so they have to turn to new technologies that can enable them to be more efficient and increase their yields.”

MapMyApple aim is to make small apple growers champions in apple growing business. Exporters of apples also saw their benefits from this because quality of apples they sell , whether its from their orchards or other orchards, can be better and of course the price can be higher!

Over 3,200 exhibitors and over 78,000 visitors

MapMyApple certainly will be your partner in that mission when it comes to apple growing business!

Common Diseases of Apple Trees

Apples are subject to a variety of diseases that can cause minor cosmetic damage or more significant damage, such as reduced yields and even tree death. Fortunately, home growers can avoid most diseases by planting disease resistant varieties. Below are a few of the most common apple diseases:

APPLE SCAB

Apple scab is one of the most common and most serious diseases that afflict apple trees. It usually appears in early to mid-spring and is more prevalent during rainy weather. The disease is caused by the fungus Venturia inqequalis, which overwinters in infected leaves left on the ground. The fungus spores are released in the spring during wet weather and are blown by the wind onto vulnerable, newly emerging leaves.

Apple scab first appears as small, olive-colored lesions on the undersides of the leaves. As the fungus spreads, the top sides of the leaves develop lesions, as well, that may become black or mottled with defined edges. Severely infected trees may become defoliated by mid-summer, making the tree vulnerable to other diseases. The fruit develop black or brown scabs or soft areas. The scabs may appear hardened and cracked, but don’t usually affect the inside of the fruit.

Several apple varieties, including Jonafree, Liberty, Enterprise, Pristine and Williams Pride are completely resistant to apple scab. Choose scab resistant varieties, especially if apple scab is a frequent problem in your area. Avoid Red Delicious, Cortland, McIntosh and Rome Beauty, which are all susceptible to the disease. Promptly rake up and remove leaves and debris in the fall and spray susceptible trees with fungicide in early spring, such as lime sulfur, sulfur or Captan.

FIRE BLIGHT

Fire blight is a bacterial disease that runs rampant in many parts of the U.S. and is difficult to control. Trees infected with fire blight may have water stained, brown blossoms and brown leaves. The twigs and the branches of the tree may turn brown or black and have open cankers that ooze a thick, brown liquid. The twigs may also turn downward at the tips to resemble a shepherd’s crook. The disease overwinters in infected wood and is spread in the spring through rain and insects.

Plant resistant varieties, such as Jonafree, Liberty, Pristine and Williams Pride and avoid susceptible varieties, including Beacon, Granny Smith, Jonathan, Gala and Fuji. Fertilize the tree in early spring before growth starts and avoid applying excessive fertilizer, which will promote rapid, lush growth that is most susceptible to infections.

Remove infected branches in late winter, while the tree is dormant. Pruning the tree while it is actively growing will likely spread the disease. Burn the branches if possible to kill overwintering bacteria. Do not leave them on your property. Currently, no sprays are recommended for home orchards, according to Ohio State University Extension.

CORK SPOT

Cork spot may resemble hail or insect damage, but is caused by low soil pH and subsequent calcium deficiency. Cork spot appears as small dimples on the skin of developing apples. The dimples spread to ½-inch wide and may appear corky or soft. The fruit is edible, but the spots reduce its aesthetic appeal.

Add lime to the soil, according to the recommendations of a soil test analysis, if the pH of your soil falls below 6.0. Spray the trees with calcium chloride at a rate of 1.5 tablespoons calcium chloride per gallon of water per tree. Make four applications, beginning immediately after full bloom. Reapply the solution every ten days to help control cork spot.

POWDERY MILDEW

Powdery mildew is caused by the fungus Podosphaera leucotricha and develops first as white, felt-like growths on the undersides of leaves. As the disease spreads, it causes wilted leaves, stunted growth and black pinpoint specks on the leaves and twigs.

Avoid susceptible varieties, including Granny Smith, Jonathan, Rome and Cortland. Plant the trees in full sun and allow plenty of space between them for good air circulation. Spray the trees in early spring with Myclobutanil, lime sulfur or sulfur.

RUST

Rust is an interesting disease because it requires a host plant, such as cedar, quince or hawthorn to develop. The fungus develop in large galls or growths found on the host plant. In spring, the galls dry, releasing the spores into the air where they are carried to apple trees. Rust causes yellow or orange spots on the leaves and distorted or mottled fruit.

To control rust, grow resistant apple varieties and remove any nearby host plants. The spores can travel up to two miles, though, so any neighboring plants may infect your trees. Spray apple trees with sulfur, Myclobutanil or lime sulfur.

BLACK ROT AND FROG EYE LEAF SPOT

Black rot and Frog Eye leaf spot refer to the same disease at different points in the disease cycle. The disease, caused by Botryosphaeria obtuse, first manifests as brown spots on the ends of the fruit. The spots enlarge in concentric circles and eventually turn black, rotting the fruit. Leaves may become covered with small brown spots or holes. Later, the disease spreads to the tree limbs, causing cankers which can eventually kill the tree.

To combat this disease, prune out all infected tree materials and burn or discard immediately. Trees infected with fire blight disease may become weakened making them more susceptible to Black Rot. Spray the trees with Captan or sulfur while the disease is in the early stages.

Key points in apple production

How important agro-measures are?

Without the application of agro-technical measures at the right time, good quality and yield can not be expected. However, fruit growers face one serious problem. Although there are key periods in the vegetative cycle of apples during which agro measures should be taken, this doesn't mean that they are carried out only then. 

The apple requires 16 micro and macro nutrients, and of course water and light should be added to this. Intensive production simply requires constant adjustment-optimization of production conditions. 

The fundamental problem for fruit growers is of organizational nature. The number of factors that affect the quality and fertility of fruits is huge, very often independent of man, and it is extremely difficult to regularly monitor and predict everything. 

The technology can make every day in orchard more efficient.

Fertilization

The technology can make it easier to calculate optimal consumption of basic elements that are necessary for proper fertilization. 

It is known how much nutrients the plants need, and on the basis of its size and vegetative mass, it can be calculated how much of nutrients should be spent in the season. Chemical soil analysis can give us initial information on what we are dealing with. But it is necessary to perform calculations so that the application of measurements give optimal results. If we run these calculations manually, we will just be wasting time. 

MapMyApple provides fertilization plan (recommended preparations and their quantities) based on previously calculated amounts of nitrogen, phosphorus, potassium, calcium and magnesium. 

Irrigation

When the water regime is concerned, digital technology can, based on the vegetative mass of trees, calculate in the short term how much water the plants need for optimum development. In addition, thanks to the internet, availability of data, satellite monitoring of weather conditions, irrigation can be fully adjusted to the amount of precipitation, sunshine and even wind, and the adjustment can be done on a daily basis.. 

According to expected precipitation and average daily temperatures, MapMyApple proposes daily irrigation plan.

Spraying

Even the appearance and protection against pests can be improved by the use of digital technologies. The onset of disease and pests are significantly affected by climatic conditions. It is not a question of whether it will appear, but the probability that certain diseases and pests will occur, according to existing weather conditions. 

MapMyApple advises how to deal with pests and diseases. Plan includes the products and quantities to be applied, through the spraying plan.
