Eggplant pests and how to deal with them

Eggplant pests and how to deal with them

Eggplants were brought to Europe from distant India several centuries ago. During this time, dark-fruited nightshade successfully took root in the beds and became a frequent guest on the tables of our compatriots.

Most summer residents plant eggplants along with peppers, tomatoes, cucumbers and other common crops, but it is not so easy to achieve a good harvest. Like any other garden plant, representatives of the nightshade family are constantly attacked by dangerous pests.

Dangerous insects

Eggplants can be exposed to bacterial, viral and fungal infections, and in addition, pests can cause great damage to the crop.

  • For example, slugs - gastropod mollusks, which multiply rapidly in rainy weather, are capable of spoiling most of the fruits in a matter of days.
  • Plants are very painful Medvedka attacks. This is not only a very ugly and even scary insect, it also leaves the plant with practically no chance for full growth and development. Medvedka moves along the underground passages dug by her and feeds on the roots of vegetable crops. This causes the plant to weaken, wither and eventually die.
  • Causes a lot of inconvenience whitefly, which for its attack prefers only the strongest and healthiest bushes - this insect lays its eggs on leaf plates. After 10 days, larvae appear from them, which suck out all the vital juices from the green parts.

In leaves damaged by pests, fungal pathologies often develop, the leaves turn yellow and curl, and the fruits stop developing. But the greatest harm is caused by such pests known to any summer resident as the Colorado potato beetle, spider mites and aphids.

Colorado beetle

Colorado beetles are well known for their voraciousness: they can destroy all the fruits of eggplant in a week or two and nullify the work of people who grow this crop. The beetles are up to 7mm wide and 10mm long, fly well and can pretend to be dead if knocked off branches. In addition, they can "hold their breath" when in contact with water, and are also resistant to most chemicals, so getting rid of them is quite problematic.

With the onset of spring, the beetles crawl out of the ground to the surface (usually this happens in May) and begin to lay eggs. Females are distinguished by exceptional fertility - each can lay from 800 to 2000 eggs per season, hatched larvae can reach a length of 16 mm. At the same time, they are characterized by increased activity - literally in 20 days they go through all the stages of their formation and are transformed into an adult.

It has been established that 40 larvae are able to completely gnaw all the leaves and green tops of the shoots of a strong adult eggplant bush. The invasion of the Colorado potato beetle is often compared with a raid of locusts - since in this case only gnawed skeletons remain from bushy plantings.

Aphid

Probably, there is no such gardener who has never encountered aphids. It infects most horticultural and horticultural crops, and eggplant is not a happy exception.

In total, there are about 30 varieties of this pest; they feed on young plants both in open ground conditions and in greenhouses. The insect is dangerous for its fertility - it gives up to 20 generations per season, while both adult insects and their larvae cause harm.

Insects pierce young shoots, leaves, as well as flowers and developing fruits and suck out the juice from them. This leads to a significant slowdown in the growth and development of the culture, and in the absence of any control measures, the plant begins to bend, the leaves turn yellow, curl and fall off. Unripe fruits most often crumble, and those that remain acquire an ugly shape, and their size is far from expected. In greenhouses, aphids attack eggplant very often, and in open areas - only in warm rainy weather.

spider mite

Pest of eggplant and many other vegetables of the nightshade family. The danger lies in the fact that it is quite difficult to detect: it exists extremely secretly. You can notice its traces only on a sunny day, and even then - with a careful and careful examination.

The action of the pest is indicated by light small bite points on the leaf plates. As the colony of insects increases, the dots transform into large spots, they subsequently give the leaf the so-called marbled color. After that, you can already notice a web on the back of the sheet, and under it - ticks. These insects reproduce quite quickly, especially favorable conditions for them are hot and dry days.

Leaves that have been affected by a tick lose their strength, dry out and crumble in the shortest possible time. Weakened plants die within a couple of weeks, if the fruits have already begun to ripen by that time, there is a chance to harvest a small crop. But if the eggplant encountered a pest in the early stages, then the plant will not have time to form fruits.

How to get rid?

When exposed to pests, it is very important to take prompt measures to combat them - insects are very prolific. They lay many eggs, and the larvae quickly grow and breed again. If you delay, the plant will simply die. Treatment of leaves, stems and underground parts of the plant should be started as soon as you notice the pest.

Folk recipes

Folk methods have proven themselves very well. For the most part, they boil down to the preparation of fermented infusions of herbs and their further spraying of diseased crops. However, a single spraying is not enough, and multiple spraying is not as harmless as it might seem at first glance. For example, frequent treatment with tobacco dust, hemlock infusion and potato tops can cause damage to a plant, especially if these plants have previously been sprayed with chemical reagents for diseases.

More gentle, but no less effective means are decoctions of wormwood, chamomile and yarrow - they have a pungent odor that repels many insects. A decoction of walnut leaves has proven itself very well, such a composition is prepared in advance: in the fall they fill a barrel with foliage, pour it with boiling water and tightly cork it with a lid.During autumn, winter and spring, the leaves are infused, and thus a concentrated solution is obtained, which serves as the basis for the preparation of a working spraying agent: 1 liter of the concentrate is dissolved in a bucket of water and the culture is sprayed with the resulting composition.

The composition may turn out to be too strong, so for starters it is recommended to spray one bush and observe the reaction of the culture within 3-4 hours. If no signs of oppression are found, all other plantings can be sprayed, otherwise water should be added.

Many summer residents note that aphids can be fought with a decoction of ash or shedding with fly ash. To do this, 1.5 cups of burnt coal are dissolved in one bucket of water and kept for a day, after which they filter and pour over the plants. Many add a little laundry soap to the substrate - then the infusion will stick better to the leaves.

Pretty good reviews received a complex solution, which is prepared as follows:

  • grind in a blender or scroll through a meat grinder one glass of onions, garlic cloves and green dandelion leaves;
  • the resulting composition is poured with a bucket of water with the addition of a couple of tablespoons of green soap;
  • the solution is left to infuse for 2-4 hours, after which the green parts of the plant are filtered and sprayed.

This tool has proven itself in the fight against aphids, as well as the Colorado potato beetle and spider mites at any stage of development. There are quite a few different collections and infusions, while they have different effectiveness, so it is better to test each of them and choose those that give the most noticeable effect.

professional tools

The modern market of agricultural technology offers a large selection of ready-made plant protection products, and effective biological preparations are not the last here. These are called bioinsecticides and quickly kill any sucking pests during the larval stage. The most common drugs from this group are Basamil, Bitoxibacillin, Fitoverm and Lepidocid are also in demand among summer residents. The preparations have a wide spectrum of action, they are used not only for vegetables, but also for spraying berry and fruit trees and shrubs.

Fungal-based preparations have good efficiency, which can get rid of pest problems even at the harvesting stage. Among these drugs, Aktofit is in the greatest demand. But at the stage of growing seedlings and moving into open ground, the fight against nematodes is especially important, for this most often they choose "Metarizin" or "Pecilomycin".

Keep in mind that fungal preparations have proven effectiveness strictly at temperatures above 25 degrees and in a humid environment, so spraying should be done after heavy watering in the morning or evening. Avoid direct sunlight - under the influence of ultraviolet radiation, the preparations lose their insecticidal characteristics.

If biological products cannot save seedlings, then it makes sense to use chemical protection products. Most often, eggplants are sprayed with Aktara, Vertimek, Confidor Extra and other preparations. Such treatments can be carried out only at the first stages of the plant's life - after flowering and the beginning of the formation of the ovary, the treatment must be stopped.Chemicals are highly effective, so most often 1-2 treatments are enough.

Against the whitefly, Fitoferm, as well as Iskra Bio, have proven themselves well. From the Colorado potato beetle, a single spraying with the preparations "Aktarina", "Phosbecid" and "Sonnet" helps, and from the whitefly - "Confidorm". Spider mites and adult aphids need to be treated with Karbofos.

Preventive measures

Proper prevention is of great importance in the fight against vegetable pests, which allows you to protect and protect the plant from insect attacks. It assumes the fulfillment of simple conditions:

  • processing of seed material before planting;
  • regular disinfection of the soil before planting seedlings, as well as after harvesting;
  • separate cultivation of vegetables that can attract garden pests;
  • timely destruction of the affected parts of the plant;
  • constant monitoring of plants for pest infestation;
  • removal of weeds and burning of plant residues;
  • compliance with the irrigation regime;
  • application of potash-phosphorus fertilizers with exact dosages;
  • in closed greenhouses, regular ventilation is necessary;
  • the correct selection of neighbors in the garden.

Modern breeders are constantly working to create varieties that are resistant to common pests. The most resistant to insects are such types of eggplants as "Purple Miracle", "Bagheera", "Bourgeois", "Nutcracker", "Ping-Pong", "Hippopotamus", as well as "Dwarf Early".
