Fruit growers in Šumadija are facing challenges in the final phase of apple production because the third generation apple curler has appeared, and there is also the danger of various fungal diseases. According to the announcement of the Agricultural Advisory and Expert Service of Kragujevac (PSSS Kragujevac), egg-laying and hatching of larvae of the third generation of the apple curler were observed in the area of the municipalities of Topola, Kragujevac and others in the Šumadija District.
The varieties Ajdared, Greni Smith and Golden Delicious, which dominate in this region, are currently in the ripening phase. However, due to high temperatures and intense solar radiation, insufficient coloring of the fruits can occur, which can delay the harvest. In addition, these conditions cause the appearance of burns on the fruits and their premature decline.
Considering the predicted rainfall, it is recommended to carry out final treatments to prevent the occurrence of fungal diseases that can cause fruit rot, bitter rot and soft rot, which can also be a problem during storage. It is recommended to apply fungicidal treatments before precipitation, using preparations advised by the profession.

The apple curler (Cydia pomonella) is a serious threat to apple orchards at this stage. Egg laying and hatching of third generation larvae is currently underway. In order to prevent larvae from burrowing into the fruit, fruit growers are advised to apply insecticide treatment with adequate preparations, such as Sever insecticide (emamectin-benzoate) in a concentration of 0.25-0.3%, with a waiting period of 7 days. It is recommended that the treatments be performed in the evening hours to avoid high daytime temperatures that can negatively affect the effectiveness of the treatment.
In addition to protection from insects, fruit growers should also focus on protection from fungal diseases. These include:
- brown rot (Monilinia fructigena)
- gorka trulež (Collectotrichum gleosporioides)
- other types of fruit rot (Penicillium spp.).
In order to ensure adequate protection, it is recommended to apply fungicides such as Aseria in a concentration of 1 l/ha with a waiting period of 3 days.
Fruit growers must be careful when applying pesticides, taking into account the grace period and the maximum number of treatments during the growing season. In plantations where harvesting is in progress or is planned soon, the application of chemical measures is prohibited. This ban would ensure the safety of the fruits and avoid potential harmful consequences for human health. These recommendations are intended to help fruit growers successfully finish the season and ensure high quality fruit ready for market, with minimal losses due to pests and diseases.
