Apple fruit fruit
Apple fruit - description, development cycle
Apple fruitis a butterfly from the leafy family. The caterpillars wintering in the bark of trees in the second half of May, after the trees have blossomed, develop into gray butterflies that fly after dusk. The departure of moths from wintering caterpillars takes 4-6 weeks. Adult females lay their eggs on apple and pear fruit and leaves. The development of the pest is favored by a sunny and warm spring, with temperatures above 15 ° C. Lower temperatures as well as strong winds and downpours make its existence much more difficult.
Caterpillars hatch from the eggs within a few to several days, which then bite into the fruit, causingworming of applesand pears, and also contaminating the fruit with their lumpy faeces. Damaged fruit falls off trees prematurely.Worms in applesspend 3 to 4 weeks, then pupate, and from July to mid-August, the second generation of moths begins to fly. Apple damage caused byapple fruitof the second generation concerns late apple varieties and is favored by warm and late summer. A pest of apple trees with a similar name but causing slightly different damage to fruits is the apple fruiting body. Let's be careful not to confuse these pests with each other.
Apple fruit - combating
Fighting apple fruitis primarily picking and destroying fruit damaged by caterpillars before they turn into butterflies.
Note!Damaged apples and pears with caterpillars inside must not be thrown onto the compost, because the pest in the composter will overwinter and will produce another generation in a year. It is best to burn them or bury them deep.
We can fight apple fruitin allotment and home gardens by installing bands on apple and pear trunks at the beginning of July. We can use 2 types of bands:
- Corrugated paper bands- you can buy corrugated cardboard in rolls or use old unnecessary cardboard boxes.
- Sticky bands- ready-made sticky bands in the form of a tape covered with glue on both sides, one side sticks to the tree, and on the other side they will stick to wandering along the trunk insects.

At the beginning of July, we wrap trunks and thicker tree branches with corrugated cardboard and tie them with string to keep them sticky. Then some of the pests, looking for hiding places in the bark of trees, will get under the bands. The bands are removed after harvesting the fruit and destroyed by burning it. If we protect beneficial insects and are able to recognize them, we can remove e.g. ladybugs from the bands before burning them. If we use sticky bands, there will be no chance of saving beneficial insects that stuck to the band. On the other hand, sticky bands are more effective in combating pests.

In the case of old, large trees that have a lot of hollows and cracks in the bark, which are a perfect hiding place forapple fruitthe effectiveness of the bands will unfortunately be low. The situation looks better among the plantings of young trees, with still smooth bark, in which the apple fruit will not find many hiding places on the branches and then it chooses a place under a corrugated paper band.
With a large number of the pest and damage to many apples, the bands themselves on the trunks, however, are not enough and it becomes necessarybug spraying in apples
Apple fruit - spraying
The first step, before we performapple spraying , is to set the correct spraying date, which unfortunately is not very easy.
How to determinedate of spraying against apple fruit ?
Now, apple spraying must be performed during the period of numerous moths' departure and hatching of the caterpillars, before they bite into the fruit. For this purpose,pheromone traps for apple fruit are hung ontrees at the beginning of May. The presence of moths in traps should be checked 2-3 times a week until mid-August. Each time the sticky floor should be cleaned with a pair of tweezers or a sharp stick, and if the adhesive surface becomes dirty or the glue has dried out, the trap must be replaced. According to the instructions, it is replaced twice a season (every 5-6 weeks).
The firstspraying for worms in applesshould be done 3 weeks after finding regular butterfly flight (usually around the turn of May and June), and after another 3 weeks spraying should be repeat.
In late apple varieties, we also fight the second generation of fruit plants by sprayingagainst apple fruitfor two weeks after finding an increase in the number of butterflies in pheromone traps, which will usually fall in the second half July.
In allotment and home gardens it is worth choosing plant protection products that are safe for the environment and selective against beneficial insects.
ThereforeI recommend the most natural remedy against fruit- infusion with mugwort wormwood. For this purpose, 300 g of fresh mugwort herb or 30 g of dried herb are poured over with 10 liters of water and boiled for 30 minutes. After cooling down, it can be sprayed. It can be used both after the presence of the pest is detected and preventively (it is best to perform preventive spraying at the end of May).
Anothereffective against applesauce is spraying horseradish infusionFor this purpose, 300 g of fresh horseradish leaves and roots are poured over with 10 liters of boiling water and allowed to cool. We use without dilution. Horseradish spraying, although a little-known method, is great in theecological fight with apple fruit
If we are unable to prepare preparations from plants and weeds ourselves, you can useplant protection agents to combat fruit fruits on apple trees , such as:
- Mospilan 20 SP - in order to combat fruit flakes on apple trees, 2 g of the agent is dissolved in 5-9 liters of water, which should be enough to spray about 100 m² of the cultivated area.
- Deltam (formerly sold under the name Decis) - this anti-fruit agent is used by dissolving 4-5 ml of the preparation in 10 liters of water. The recommended spray rate per 100 m² is 6-15 liters depending on the size and number of plants.
- Karate Zeon 050 CS, which is used in the proportion of 3 ml for 5-7.5 liters of water.
Remember, however, to use chemicals in the garden as a last resort due to the harmfulness of these agents to the environment and beneficial insects, especially that in the case ofapple fruitwe have a natural alternative to spray. "
