Common issues for Italian buckthorn 'Argenteovariegata' based on 10 million real cases
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Leaf deformity
Leaf deformities can have a variety of causes.
Solutions: Follow these steps to revive plants with abnormal leaves. Remove damaged leaves: Plants can recover from damage when given the time to do so. Remove any deformed leaves so they don't continue drawing energy from the plant. This also creates room for healthier ones to grow. Stop using herbicide: Though herbicide damage is challenging to diagnose, gardeners can potentially prevent deformed leaves by not using any and by strictly following manufacturers instructions. Spray insecticide: Prevent pests from inhabiting plant leaves by spraying with insecticide regularly and practicing good natural pest prevention techniques. Apply a balanced fertilizer: Solve nutrient deficiencies and excesses by using a well-balanced fertilizer (organic or conventional both work) before planting, and consider topdressing when signs of stress are apparent. Fix watering schedule: If plant leaves are curled downward due to too much or too little water, adjust the watering schedule so the soil is moist, but not damp. Remove infected plants: If the plant has succumbed to a viral infection, not much can be done to revive it. Remove and destroy all compromised plant material to prevent spread to other plants.
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
Placement is often random and scattered as diseases are spread through raindrops.
May appear on lower leaves and the interior of the plant where humidity is higher.
Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
Leaf margins may turn yellow.
Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
Blotches grow in size until the entire leaf is brown.
The leaf falls off the plant.
Severe Symptoms
Partial or complete premature defoliation
Reduced growth
Increased susceptibility to pests and other diseases
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
For less serious cases:
Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.

Leaf deformity
Leaf deformities can have a variety of causes.
Overview
Leaf deformity manifests in the form of curled, cupped, or distorted leaves, often first seen in the spring. There are a number of different possibilities as to the cause and it will not always be easy to isolate the problem without laboratory analysis. In the majority of cases, however, the gardener should be able to isolate the cause through close examination of the plant and the local conditions.
Symptom Analysis
The plant has developed abnormal leaves. They may look similar to leaf curl, but show other problems such as:
stunting
abnormal shapes
a bumpy texture
gaps between leaf sections
raised growths on the top surface
Disease Cause
The causes are widespread and varied and the gardener will need to examine plants carefully as well as consider environmental factors.
Disease due to insect damage: Mites, aphids, and other insects that feast on plant leaves can leave them vulnerable to viral and bacterial disease. Some, like leaf galls and rust, produce distorted leaves. If the gardener sees insects on the plants, it is likely the insect is the culprit. Some mites are too small to see, and laboratory analysis may be required.
Herbicide exposure: Herbicides can stress plant leaves. This may lead to stunted growth and a curling, cupped appearance. Even if the plant owner didn't apply herbicides, herbicide drift and planting in contaminated soils can expose plants to these chemicals. If all plants in an area have deformed leaves, the cause is likely herbicides. Herbicide exposure is also characterized by narrow new leaves.
Less than ideal growing conditions: If plants are exposed to cold temperatures right as their leaves are coming out of the bud, they might become stunted and malformed. If deformed leaves occur right after a cold spell or frost, this is likely the cause. Too much and too little water can also cause deformed leaves. Leaves curling down but not distorting is more likely to be a watering issue than a leaf deformity.
Nutrient deficiencies: A lack of critical nutrients during the growing phase, including boron, calcium, and molybdenum, may lead plant leaves to grow stunted or disfigured. If a nutrient deficiency is to blame, the leaves will also show discoloring.
Fungal infections: a variety of fungal pathogens can distort leaves, as is the case with Peach leaf curl.

Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
Both leaves and blossom on the tips of branches will go brown and wither.
Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
Any fruit that does appear will turn wrinkled and fail to develop.
Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.

Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
Maintain good air movement between plants through proper plant spacing.
Increase air circulation through the center of plants through pruning.
Thoroughly clean all pruning tools after working with diseased plants.
Never dispose of disease plant material in a compost pile.
Avoid overhead watering to keep moisture off of the foliage.
Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Provide the proper amount of water. Water until the soil is moist, but not damp. Only once the soil dries out, should the plant be watered again.
Protect plants from cold. Bring plants indoors or protect them with frost cloth when bad weather is forecast.
Avoid herbicide exposure. If the gardener or surrounding neighbors are applying herbicides, consider moving vulnerable plants to where they are less exposed to any chemicals that may be carried on the wind.
