Spider mite on eggplant: signs of damage and methods of control


The spider mite (from the Latin Tetranychidae) belongs to the family of ticks from the superorder Acariformes, or Prostigmata, and is a very frequent visitor to garden crops and garden crops and causes significant damage to garden crops. There are several ways to deal with spider mites on eggplant, but you should not forget about effective preventive measures.

Signs of defeat

Tetranychidae spider mites most often populate the lower side of eggplant foliage, where areas with an invisible web are formed. Also on the leaves you can see the plant parasite itself. Cellular plant sap is used to nourish the spider mite colony, resulting in the appearance of small, whitish dots. Both adult plants and eggplant seedlings are affected.

Thus, as a result of the defeat of Tetranychidae, the garden culture becomes very weakened and is unable to fully resist the various infections transmitted by plant parasites. Spider mites often become carriers of spores of gray rot and dangerous viral diseases. Particularly active pests such as spider mites breed in the presence of low humidity and high temperature conditions.

Spider mite on eggplant: methods of control

Greenhouse and outdoor protection

Diseases affect eggplants in a greenhouse about as often as they do on ridges of open ground, so greenhouse plants cannot be completely immune from damage by a spider mite. The pest in a very short time is able to attack significant planted areas and reduce the overall yield. In some cases, complete death of the plant is observed.

That is why it is very important to timely detect the lesion and get rid of the plant parasite as quickly and efficiently as possible. You can fight Tetranychidae with both folk remedies and chemical preparations. The choice of treatment method depends on many factors, including the features of the vegetative period and the level of damage to garden plants.

The best folk remedies

Folk remedies are sufficiently effective, but are used to prevent pest damage or to combat the small number of plant parasite in vegetable crops.

Name of facilityCooking methodApplication features
Concentrated Soap SolutionIn 10 l of warm water, dilute 200 g of laundry soap grated. The solution is insisted on the order of two hours, stirring occasionally until the soap chips are completely dissolvedTreat the bottom of the leaves. Apply once a week, regardless of the stage of vegetation
Herbal infusion with soapMix 250 g chopped in a meat grinder dandelion leaves, garlic and onions. Pour a bucket of water and add 25 g of chopped laundry soap. Insist for 3-4 hours in a warm placeStrain the resulting plant infusion and treat the plant leaves in the evening once a week
Medical Ethanol 70%Ethyl alcohol can be replaced with ammonia, 30 ml of which must be diluted in 1/2 bucket of warm water and add chopped laundry soapIt is important to remember that alcohol spraying or wiping does not always contribute to the complete disappearance of the pest.
Soap-alcohol solutionDissolve about 20-30 g of ground laundry soap in 1 liter of boiling water, cool and pour about 10-20 ml of alcoholVery carefully treat the eggplant leaves on both sides with a solution in the evening
Yarrow infusionApproximately 0.75 kg of dry yarrow leaves pour 10 liters of boiling water, mix and insist for two to three daysSpraying the whole aerial part of the eggplant in a greenhouse or on ridges of open ground

Topical Chemical and Biological Preparations

Strong modern chemicals, represented by pesticides and insectofungicides, have a fairly high level of toxicity, which makes their use not possible at all stages of the vegetable growing season. However, subject to the instructions for use, the chemical components are not able to accumulate in the crop, which makes it possible to obtain environmentally friendly vegetable products. In the conditions of home gardening, low-toxic biological agents are also popular.

Drug nameCooking and consumptionTerms of use
Biological product "Apollo"Long-acting contact acaricide. 2 ml of the drug must be dissolved in 5 l of waterTwo treatments should be carried out throughout the growing season.
Biological product "Actofit"Highly specific natural neurotoxin for outdoor and indoor use. 4 ml solution per 1 liter of waterTwo treatments should be carried out throughout the growing season.
Biological product "Acarin"Dilute 1ml of the drug in 1 liter of water and use at the rate of one liter per ten square meters of landing areaSpray the aerial part in calm and dry weather with a freshly prepared solution.
Biological product "Vermitek"Dilute the drug in a ratio of 2.5-3 ml per 10 l of warm waterReprocessing is carried out one week after the first
Biological product "Fitoverm"Dilute 10 ml of the drug in 10 l of warm water. This amount is spent per hundred square meters of landing areaSpray garden crops in calm and clear weather. Two treatments are needed in two weeks.
Acaricide "Envidor"Dilute 2-3 ml of the drug in 5 l of waterTwo treatments should be carried out throughout the growing season.
Fungicide "Tiovit Jet"An analogue of the well-known colloidal sulfur to vegetable growers, which has very good solubility in water. Dilute 40−50 g per bucket of waterProcessing is carried out at least three to four times during the growing season
Insecticide "Bi-58"To prepare the working solution, two ampoules of the drug per ten liters of water should be used.Reprocessing is carried out three to four weeks after the first spraying
Acaricide "Sunmight"It has a long action for a month and a half. It is necessary to dilute 1 g of powder in 1 liter of waterSpray the aerial part in calm and dry weather with a freshly prepared solution.

Lesion prevention

In order to minimize the risk of eggplant damage by spider mites, timely prevention and protection of vegetable crop plantings is used.

Prevention of damage by a spider mite of the greenhouse culture or when growing on ridges of open ground consists in the following measures:

  • regular weeding and loosening of greenhouse soil;
  • crop rotation in closed ground;
  • thorough digging of the soil in a greenhouse or greenhouse in the fall, immediately after harvesting;
  • maintaining a high humidity level in the greenhouse;
  • regular watering of plants and mulching of the soil;
  • systematic examinations of the underside of leaves;
  • removal and destruction of leaflets most affected by the pest.

How to protect eggplant from pests

It should be remembered that spider mites reproduce most quickly in dry and hot weather, therefore it is important to observe the irrigation regime and to prevent air drying inside the greenhouse structures.
