Embodiment 1

[0024] Embodiment 1, eggplant is cultivated in autumn and winter in the solar greenhouse, and the eggplant is cultivated according to size in the solar greenhouse, with a large row spacing of 80cm, a small row spacing of 60cm, and a plant spacing of 48cm;

[0025] 15-20 days before eggplant planting, transplant Mingyuecao; plant a row of Mingyuecao in the middle of the planting row, with a plant spacing of 28cm; open holes for colonization, mix 75g of carbonized rice husks in each hole, and plant Mingyuecao in the holes.

[0026] The seedlings of Mingyue grass are raised with a plug substrate. The substrate is composed of peat: carbonized rice husk: vermiculite in a volume ratio of 2:1:1. Mingyue grass is raised 25-30 days earlier than eggplant, and 25 days before transplanting. Mix 17.5g of %thiamethoxam water-dispersible granules with 30kg of water and dip in the plug for 2-3 minutes, so that the matrix in the plug is completely soaked by the medicinal solution.

Embodiment 2

[0035] Example 2. Eggplant was cultivated in autumn and winter in a solar greenhouse. The place was in an eggplant greenhouse in Shouguang, Shandong Province. It was sown on July 10, 2014 and planted on August 15. The variety was Dalong. There are 2 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0036] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0037] Treatment 2: Cultivate eggplant according to the following method, and adopt existing chemical methods to control Bemisia tabaci. The specific technical scheme is as follows: when the eggplant is transplanted, use 17.5g of 25% thiamethoxam water-dispersible granules mixed with 30kg of water to dip the hole plate for 2-3 minutes, so that the matrix in the hole plate is completely soaked by the medicinal liquid. Foliar spraying of thiamethoxam for lice occurrence. The eggplant planting density was the same as treatment 1.

Embodiment 3

[0040] Example 3, eggplant was cultivated in autumn and winter in a solar greenhouse at a certain vegetable base in Shouguang, Shandong. Sowed on June 28, 2015, and planted on July 30, the variety is Burita. There are 3 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0041] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0042] Treatment 2: Except that the seedling substrate of Mingyue japonica is composed of peat: vermiculite at a volume ratio of 3:1 and that carbonized rice husks are not mixed in the planting hole of Mingyue qingming, other measures are the same as treatment 1.

[0043] Treatment 3: Except that the mixed aqueous solution of lettuce extract and chitin is not sprayed on eggplant seedlings 1-2 days before planting and the mixed aqueous solution of lettuce extract and chitin is not sprayed on the leaves 25 days after eggplant planting, other measures are the same as t...

Abstract

The invention discloses a method for prevention and treatment of eggplant bemisia tabaci. According to the invention, eggplant is cultivated in a solar greenhouse according to large and small rows, wherein large row spacing is 80 cm, and small row spacing is 70 cm; gynura divaricata is transplanted in 15 to 20 days before field planting of the eggplant, wherein a row of the gynura divaricata is planted in the middle of a small planting row, and plant spacing is 28 cm; a carbonized rice husk contained substrate is adopted for seedling raising of the gynura divaricata in plugs, wherein carbonized rice husk is additionally applied into a planting plug, and a thiamethoxam pesticidal liquid is adopted for plug dipping and root irrigation; and in 1 to 2 days before field planting of the eggplantand in 25 days after field planting of the eggplant, a mixed aqueous solution of an approach-avoidance plant lettuce extract and chitin is adopted for foliage spray. The method provided by the invention can exterminate bemisia tabaci before the bemisia tabaci is diffused to the eggplant by utilizing a trap plant namely the gynura divaricata and a directional covert pesticide application technology, can reduce the usage amount of a chemical pesticide and realize non-contact chemical prevention and treatment for the main crop eggplant at the same time, and guarantees food safety and ecologicalsafety.

Description

technical field [0001] The invention relates to a control method of eggplant insect pests, especially a control method of eggplant bemisia tabaci which can reduce the use of chemical pesticides and realize non-contact chemical control of main crops. It is especially suitable for the cultivation of eggplants in autumn and winter in solar greenhouses and belongs to plant protection. technology field. Background technique [0002] Bemisia tabaci belongs to the family Amiptera of Homoptera. Adults and nymphs mainly suck the juice of plants, causing chlorosis, wilting or dead leaves of the affected leaves. At the same time, they secrete honeydew to induce soot, affect the photosynthesis of plants, and make plants grow bad. Bemisia tabaci can also transmit a variety of plant virus diseases. In recent years, the pest damage has increased year by year. Due to the fast reproduction speed of the insect, serious overlapping of generations, wide range of hosts, fast transmission and ...
