Embodiment 1

[0013] Embodiment 1: Auraptenol is to the control of agricultural fungal disease

[0014] The tested strains Fusarium graminearum (Fusarium.graminearm) were isolated from wheat head blight; F.oxysporum (F.oxysporum) were isolated from cucumber wilt diseased plants; solani) was isolated from rice sheath blight leaves; Rhizoctonia solani was isolated from wheat sheath blight leaves; Sclerotioia selerotiorum was isolated from rapeseed Sclerotinia strains; F. moniliform was isolated from rice bakanae diseased ears; pepper anthracnose fungus (Colletotrichum capsici) was isolated from pepper diseased leaves; botrytis cinerea was isolated from cucumbers; ) from tomato early blight diseased leaves; capsicum phytophthora capsici from pepper diseased plants. The test agent Auraptenol (isolated and identified from Angelica dahuricae), was dissolved in acetone to make a 1000 μg / mL mother solution, and stored at 4°C for later use. PDA medium: cut 200g of peeled potatoes into pieces, boil...

Embodiment 2

[0019] Example 2: Auraptenol as an active ingredient in the control of agricultural pests

[0020] The source of the tested insects was the 3rd to 6th instar larvae collected from the field population, raised indoors with artificial feed until pupation and oviposition, and selected indoor F1 and F2 generation larvae with basically the same size for toxicity testing (among them, cabbage caterpillars were collected from the field). population). Accurately weigh Auraptenol (isolated and identified from Angelica dahuricae of Umbelliferae), dissolve it in acetone, and make a test mother solution with a concentration of 2.000 mg / ml, and then dilute it with 1‰ TritonX-100 water emulsion into 6 different concentration as the test solution. Fresh and clean cabbage leaves (wherein, armyworms use wheat leaves and tea geometrids as fresh tea leaves) are made into leaf discs with a diameter of 1.5 cm with a leaf topper, and then they are soaked in the test liquid for 10 seconds and then t...

Embodiment 3

[0025] Auraptenol, lignin, diatomaceous earth and other conventional auxiliary materials were weighed to prepare a wettable powder with an active ingredient concentration of 2% according to a conventional process.

Abstract

The invention discloses use of a natural compound Auraptenol as an agricultural bactericide or pesticide. The Auraptenol can be taken as the pesticide for preventing and treating Lepidoptera and homopetera insects or the bactericide for preventing and treating agricultural fungus diseases, and especially has remarkable control efficiency for sclerotinia rot of colza, fusarium wilt of cucumber, rice sheath blight disease, scab of wheat, anthracnose of hot pepper, rice bakanae disease, wheat sharp eyespot, tomato late blight, gray mold and the like. The Auraptenol as the agricultural bactericide or pesticide is good in effect, broad in spectrum, low in toxicity, free from residue, non-pollution and nuisanceless, and is especially in favor of environment protection.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to the use of a natural compound Auraptenol as an active ingredient to prepare agricultural insecticides or fungicides. Background technique [0002] Agricultural pests occur in a large area in many areas of our country, and the frequency is on the rise, and the damage is aggravated. At present, chemical pesticide control is still the main control measure. Due to the long-term use of chemical pesticides, the pests have developed varying degrees of resistance to various chemical insecticides such as organochlorines, organophosphorus, carbamates, and pyrethroids, and the control effect has declined significantly, forcing farmers to increase The dosage is to improve the control effect, but it reduces the safety of agricultural products. [0003] In addition, in agricultural production, pathogens that harm crops include fungi, bacteria, viruses, etc. Among them, fungi ...
