Example Embodiment

[0029] The extract is made from the freshly harvested wattle, poplar leaves and wormwood as well as rhizomes and leaves. The preparation method includes the following steps:

[0030] ⑴ Collect the wattle, poplar leaves and wormwood together with the roots, stems and leaves, remove impurities and wash them for later use;

[0031] (2) Add the product of step (1) to the crusher to squeeze the juice;

[0032] (3) Filter the solid-liquid mixture after squeezing the juice, filter out the residue, and add potassium sorbate with a weight of 0.35‰ of the medicinal solution to make the extract.

Example Embodiment

[0033] Example 1

[0034] Three greenhouses were selected for planting frame beans, each of which was one mu of land, divided into three groups, each one mu, named A, B, and C respectively; the soil composition and pH of A, B and C were the same, so The temperature, humidity, wind, and light in the area are the same, the water source is the same, and the fields are managed in the same way.

[0035] The bean varieties planted in A, B and C are the same, and the plant density and management methods are the same.

[0036] A uses the agent of the present invention, B uses traditional chemical agents, and C does not use any agents.

[0037] Medium A: Using wattle, poplar leaves, wormwood and roots and leaves as raw materials, use the following methods:

[0038] (1) Mix the extract with water in a weight ratio of 1:14-15, and then add 0.1% washing powder to prepare a spray;

[0039] ⑵When controlling spider mites, choose a sunny day and spray the whole plant 1-2 times in the morning and eveni...

Example Embodiment

[0045] Example 2

[0046] Select 3 greenhouses for planting cucumbers, each of which is one mu of land; divided into three groups, each of one mu, one of which is named A, the other is named B, and the other is named C; A, B The soil composition and pH are the same as that of C, the varieties are the same, the temperature, humidity, wind, and sunlight of the area are the same, the water source is the same, and the greenhouse is managed in the same way.

[0047] Shed A uses the medicament of the present invention, Shed B uses traditional chemical agents, and Shed C does not use any agents.

[0048] The control effect of A shed was 99.56%, and the spider mites in the whole crop were completely prevented and controlled.

[0049] The control effect of B shed is about 91.85%, and the recurrence rate is relatively high.

[0050] In C, there is a large-scale reduction in production, and some cucumbers have no commercial value.

[0051] After harvesting statistics, the output of area A is 6.85%...

Abstract

The invention relates to a botanical medicament used for preventing and controlling spider mites, and a use method thereof. The raw material of the botanical medicament is an extract liquid of Herba Schizonepetae, poplar leaf and argy wormwood. The extract liquid comprises an antiseptic. Rhizomes and leaves of Herba Schizonepetae, poplar leaf and argy wormwood are adopted as raw materials and are juiced to obtain the extract liquid, the extract liquid is diluted with water, and the diluted extract liquid is sprayed on greenhouse crops in order to realize a prevention effect when no spider mites exist in the crops and realize a very good control effect when the spider mites exist in the greenhouse crops; a field test result shows that the prevention and control effect reaches 99.5% or above; the extract liquid can prevent and control the spider mites, and also can obviously prevent and control aphids, thrips and other piercing and sucking pests; and Herba Schizonepetae, poplar leaf and argy wormwood are edible and medicinal wild plants, so drug residual and environmental pollution problems do not appear in the practical use process, thereby harms of pests are reduced, and the yield increases by about 6-10%.

Description

technical field [0001] The invention belongs to the technical field of crop pest control, in particular to a plant-derived medicament for preventing and controlling spider mites and an application method thereof. Background technique [0002] In recent years, spider mites (red spider mites) have become one of the important pests that harm greenhouse crops and vegetables. Commonly damaged crops include strawberries, eggplants, cucumbers, tomatoes, peppers, cowpeas, beans, watermelons, etc.; it mainly harms the leaves, tender stems, flowers, etc. of plants. Chlorosis turns whitish, dense pale spots appear on the leaf surface, curling and yellowing the leaves. In severe cases, the plants will have yellow leaves, scorched leaves, rolled leaves, fallen leaves and death. At the same time, spider mite is also the carrier of various plant virus diseases. [0003] Tetranychus are small individuals, generally less than 1 mm in length, and nymphs can be less than 0.2 mm, but their f...
