Embodiment 1

[0029] Indoor Toxicity Determination of Botanical Pesticides to Main Pests of Jinqiu Pear

[0030] (1) The formula of the botanical pesticide is as follows:

[0031] Take 1.5% of ginkgo leaf extract, 1.5% of tung tree leaf extract, 2.5% of oleander leaf extract, 3% of arborvitae leaf extract, 2% of masson pine leaf extract, and 1% of barbarum fruit extract %, Camellia oleifera tea dry cake extract 3%, marigold root extract 2%, cypress cypress leaf extract 1%, organic silicon 1.5%, sodium benzoate 0.1%, distilled water 80.9%, add to the stirring tank and stir at room temperature for 30 minutes to obtain Compound botanical pesticides.

[0032] (2) The main pests of Jinqiu pears tested indoors were pear psyllids, pear yellow powder aphids, pear aphids, and fruit-sucking moths. All the tested pests were captured from the field, and after a period of artificial rearing in the room, the tested insects with the same size and the same age were selected for testing.

Embodiment 2

[0040] Field simulation test of compound botanical pesticides on main pests of Jinqiu pear:

[0041] From May to August 2006, it was carried out in the pollution-free production demonstration base of Jinqiu pear in Taijiang County, Guizhou. The pear tree variety was 10-year-old Jinqiu pear. 2000 times, repeat 3 times for each drug concentration treatment, each repetition is a plot, and the area of ​​the plot is 50m 2 . The treatment plots were arranged in random blocks, and the sprayed water was used as the blank control. Apply with a knapsack sprayer. Check the number of remaining living insects of pear psyllid, pear yellow powder aphid, pear aphid, fruit sucking moth 1 day, 3 days, 7 days and 15 days before and after the drug respectively, calculate the control effect, and observe the effect of the test agent on pears. tree impact.

[0042] The measurement results showed that the leaves of pear trees had no adverse effects under the treatment of botanical pesticides. Ac...
