The leafworm is a dangerous insect for garden plants. In nature, there are more than 10 thousand varieties of this pest. The pear leaf roll is an equally dangerous garden pest. Despite its small size (only 2.5 mm long), it can lay up to 500 eggs over the summer. This pest is usually yellow in color. Sometimes it can take on a greenish or dark green tint. Another important point is that the insect has a waxy coating of white.
It is imperative to fight the pear leaf roll. Otherwise, this harmful insect in the shortest possible time will fill not only the branches and leaves of trees, but can also destroy a solid part of the fruit. It multiplies very quickly. That is why gardeners are advised to systematically inspect their fruit trees. If the leaf roll has appeared in the garden, then the leaves on the plants curl. Inside each such spoiled leaf you can find whole colonies of pear leafworm larvae. Another sign of the leaf roll is the cobweb on the pear.
Leaf worm on a pear: how to fight
It is imperative to take measures to combat the pear leaf roll. Otherwise, you can lose not only the harvest of the current year, but also undermine the strength of the trees in general. Exhausted and diseased plants overwinter poorly and may die already in the first severe winter. In addition, you should not expect a good harvest from a diseased tree next year.
During this time, many pests, including the leafworm, move away from winter and wake up. This dangerous insect hibernates in the leaves, so it is the treatment of plantations in the first warm days that will give a good result and protect the garden from unexpected guests. It is worth treating the trees before flowering. Chemical preparations will give a good effect. Do not be afraid to spray the trees with "chemistry", since at this time of the year there are still no fruits in the garden, and the effect of the drug will completely end in a month. In spring, drug 30 gives a good effect. It has a good effect on pests that have overwintered in the garden. However, the treatment should be carried out even before bud break.

If for some reason it was not possible to spray the trees before bud break, then the drug 30 can be replaced with other insecticides. Atom, binomial, landing, and zolon have proven themselves well. Be sure to read the instructions and do everything strictly according to it, otherwise you may not expect a good effect. It should be remembered that the solution should not be highly concentrated in late spring. Dissolve a maximum of 1 ml of the selected preparation in 1 liter of water. In spring, one spraying will be enough for a good effect.
How to deal with caterpillars on a pear
If in the spring it was not possible to process pear plantings from the leafworm, then in the summer the trees are attacked by caterpillars - the offspring of this insect. In this case, the fight against the pest has not yet been lost. Biologicals have been gaining popularity over the past few years.
Most often, experienced gardeners trust proven biological drugs: fitoverm, lepidocid and bitoxibacillin.At the same time, experts also recommend using drugs of the pyrethroid group (fastak, aivengo, accord), however, processing should be carried out exclusively in warm weather. The air temperature, even at night, should not drop below 10 ° C. This is due to the fact that pests, as a rule, cannot stand the coolness. On days when the temperature drops, they hide in the bark of trees. As a result, spraying the trees will not give the desired effect, and with the onset of heat, the caterpillar will reappear on the pear.

It is also important to note that these insects do not like hot weather. Therefore, it is better to carry out processing on days when the air temperature is in the range from 20 ° C to 25 ° C. One spraying per season will not be enough. It is recommended to carry out at least 2, and preferably 3 sprays. In this case, they should be carried out at intervals of 7-10 days, changing the drugs.
Leaf roll on a pear: how to process from folk remedies
Traditional methods work as well as chemical and biological agents, but in this case you will have to work harder. Many summer residents install special baits on trees. You can make them from used cans or plastic bottles. Sweet compote, kvass, or already fermented wine is poured into such a bait. It is recommended to place them on trees in the evening and overnight where there is a huge number of pests, including leaf rollers. In the morning, such a device is shaken out, destroying insects, and in the evening the procedure is repeated again.
It will help well in the fight against the leaf roll tobacco. Horticultural crops need to be sprayed with a solution from this plant, but this must be done before flowering.
Some gardeners do not use the leafworm on the trees, but from time to time they go around the garden and manually collect the rolled leaves. This method allows you to almost completely get rid of the pest, but this must be done systematically. It is also recommended to whiten fruit trees every spring and autumn. It is advisable to add 1% copper sulfate to the solution with lime, which will protect the plantings not only from the leafworm, but also from many other insects. In addition, one should not forget about the trapping belts, which are fixed every spring on all fruit trees without exception.
You shouldn't dwell on just one method, you should try several options at once. Then the gardener will surely win the war with the pear leaf roll!
