Control of pests and diseases

6 min read

When caring for your fruit trees and shrubs, prevention of disease and pests is always better than cure. While pesticides are an option, it is important to consciously choose preventative measures that promote the health of the tree. Here at [Company Name], we strive to provide you with information on both prevention and control, with an emphasis on organic approaches.

Prevention is the Key #

A healthy tree is naturally more resistant to diseases and pests. Factors such as the right location, healthy soil, good water management and appropriate pruning play a crucial role. A tree that thrives in its environment will be less susceptible to diseases.

The Right Tree for your Garden #

Selecting the right tree species for your garden is of great importance. By adapting the tree to your garden, instead of the other way around, you minimize the chance of diseases. In addition, the choice of the variety is essential. Some varieties are more susceptible to diseases than others. At [Company Name] we are happy to provide you with advice on disease-resistant varieties.

Diagnosis and Treatment #

When a tree does get sick, it is crucial to identify the nature of the disease. Our website and experts can help you with this. For some diseases, treatment is not necessary and removing leaves at the end of the season may be sufficient. In other cases, rapid treatment is essential, especially when the infestation is limited.

Safe Use of Pesticides #

Although the use of pesticides is controversial, they may be necessary in some situations. However, it is essential to use only those products that are suitable for fruit and vegetable plants and to follow the instructions strictly. Safety standards are strict, if applied correctly.

At Schramas boom we strive for a holistic approach to gardening, where healthy trees and a healthy environment are central. By making conscious choices in the selection and care of your fruit plants, you can prevent many problems and enjoy a bountiful harvest. Our experts are always ready to advise you on any questions or problems with your fruit trees.

Here are some proven methods and strategies for controlling diseases and pests in fruit plants:

1. Prevention and Monitoring

  • Healthy Soil and Plants: Start with a healthy foundation. Provide a well-drained soil rich in nutrients and select healthy, disease-free plants.
  • Regular Inspections: Monitor plants regularly for signs of disease or pests. Early detection is crucial for effective treatment.

2. Pruning and Spatial Planning

  • Pruning: Keep fruit trees and shrubs well pruned. Remove dead, damaged or diseased branches. This promotes better air circulation and reduces hiding places for pests.
  • Thinning out: Thin out fruit when they are still small. This prevents overloading of the branches and promotes larger, healthier fruit.

3. Biological Control Methods

  • Natural Enemies: Encourage natural enemies of pests, such as ladybirds, parasitic wasps and predatory beetles. They help control populations of harmful insects.
  • Insect repellents: Use insect repellents based on neem oil, diatomaceous earth or other natural substances to control insect infestations.

4. Organic Fertilizers and Soil Improvers

  • Balanced Nutrition: Give fruit plants the right nutrients. Organic fertilizers and compost contribute to healthy growth and resistance to diseases.

5. Disease control

  • Selective Planting: Choose disease-resistant fruit varieties and cultivars. These are often more resistant to specific diseases.
  • Copper-containing agents: Copper-containing fungicides can be used to control fungal infections. Pay attention to the correct dosage and frequency.

6. Healthy Watering and Drainage

  • Controlled Watering: Water at the base of the plants to help the roots grow deep. Avoid wetting the leaves to prevent fungal diseases.
  • Good Drainage: Provide good drainage to prevent waterlogging, which can lead to root rot and other problems.

7. Use of Traps and Barriers

  • Fruit traps: Place traps to attract and capture insects before they can cause damage.
  • Physical Barriers: Use nets, cloth or other physical material to keep birds and rodents away from the fruits.

8. Resistant Varieties and Cultivars

  • Resistance: Choose fruit varieties and cultivars known for their resistance to specific diseases or pests.

Combining these methods into an integrated pest and disease management plan can promote fruit plant health and maximize yield. Always consider local conditions and specific plant needs when implementing these strategies.

Different types of pests and measures: #

ProblemRecognizeTypeMeasures/Solutions
BotrytisFruits rot prematurely and are covered with grayish-white, fluffy mold.MoldBotrytis, also known as gray mold, thrives in humid conditions. To prevent this, it is important to ensure that plants are well ventilated. Regular inspection and removal of affected fruit can prevent the spread. Also, ensure good air circulation and consider using fungicides.
Fire blightFlowers, leaves and young shoots turn brown-black and wither.DiseaseFire blight is a bacterial disease that can spread quickly. Prevention is essential. Prune affected branches generously and disinfect pruning tools between each cut. Provide good air circulation and avoid excessive fertilization. Also choose resistant varieties where possible.
ScabiesGray-green or olive-colored spots on leaves. Deformities and leaf loss.DiseaseScab thrives in moist conditions. Prevent leaf wetting by using drip irrigation, for example. Prune regularly to promote air circulation. Choose resistant varieties and use fungicides if necessary.
Fruit tree cancerSwollen, corky growths on branches, bark flaking off.DiseaseFruit tree cancer can cause serious damage. It is important to prune away affected branches generously and to ensure that the wound is well covered. Provide good air circulation and avoid excessive moisture. Choose healthy and well-adapted trees.
Monilia rotSoft, brown, rotting spots in the flesh. Concentric rings of cream-colored spore heaps.DiseaseMonilia rot, also known as fruit rot, can spread quickly. Harvest the fruits at the right time to avoid overripeness. Store the fruits in a cool, dry place. Avoid damage during harvest and storage. Use fungicides if necessary.
Curl diseaseLeaves become blistered and curled. Wrinkled and deformed.DiseaseCurl disease mainly occurs in peach and nectarine trees. It is important to spray preventively with fungicides when the buds swell in spring. Ensure good air circulation and avoid excessive fertilization. Choose resistant varieties where possible.
MildewWhite powder that later turns brown on leaves, shriveled and deformed.MoldPowdery mildew thrives in warm, dry conditions. Provide adequate air circulation and avoid wetting the leaves. Regular inspection and removal of affected leaves will help prevent spread. Use fungicides as needed.
Lead shineLeaves get a silver-gray sheen, branches die off.DiseaseLead shine is most common in plum and cherry trees. Prevention is important. Prune affected branches generously and disinfect pruning tools between each cut. Provide good air circulation and avoid excessive fertilization. Choose healthy trees.
Hailstone diseaseRound, brown spots on leaves.MoldShot hole disease can cause damage to stone fruits such as cherries, peaches and plums. Prevention is key. Avoid wetting the leaves and ensure good air circulation. Regular inspection and removal of affected leaves will help prevent spread. Use fungicides if necessary.
LiceLeaves are eaten or mined.PestsLice can be washed away with a strong jet of water. Natural enemies such as ladybirds and parasitic wasps can also help in the control. In more serious cases insecticides can be used, but this should be done with care to spare other beneficial insects.
CaterpillarsLeaves turn brown and fall off prematurely.PestsCaterpillars can be removed by hand or with the help of natural enemies such as birds and insects. In more severe cases insecticides can be used, but this should be done with care to spare other beneficial insects.
Fruit miteLeaf is eaten.PestsFruit mites can be controlled by using predatory mites. Applying insecticides can also be effective, but this should be done with care to spare other beneficial insects.
