Problems solved by technology

The development of new pesticides is costly and takes a long time, and will never catch up with the speed of bacterial resistance, so it is imminent to solve the problem of drug resistance
In the actual operation of agricultural production, measures such as rotation of different pesticides are difficult to achieve obvious results; crop rotation is unrealistic for perennial apples

Embodiment 1

[0018] Indoor toxicity determination and compounding ratio screening

[0019] 1.1 Test agents

[0020] 94.7% Osthole, provided by the Institute of Food Quality and Safety, Jiangsu Academy of Agricultural Sciences. Dissolve in 95% alcohol and prepare 10000mg / L mother liquor for later use.

[0021] 98% carbendazim, provided by Shandong Huayang Pesticide Chemical Group Co., Ltd. Use 0.1mol / L hydrochloric acid to make 10000mg / L mother liquor for later use.

[0022] The osthol products with a content of 10 to 90% from my country Yuancheng Science and Technology Development Co., Ltd., Shaanxi Hebo Natural Products Co., Ltd., Xi’an Sanwei Biotechnology Co., Ltd. and other manufacturers meet the requirements of the osthol used in the compound composition of the present invention. Requirements; and the carbendazim compounded with osthole is a commercially available pesticide product, as long as it meets the compounding ratio and application conditions of the present invention.

Embodiment 2

[0060] Field trial

[0061] According to the indoor compounding ratio screening experiment, osthol: carbendazim=1:35 is the best ratio. When osthol is 1mg, carbendazim is 35mg. We have made a 36% Osthole·Carbendazim suspension.

[0062] 2.1 Test reagents and community arrangement

[0063] According to "Part 118 of "Pesticide Field Efficacy Test Guidelines (II)" edited by the Ministry of Agriculture Pesticide Inspection Institute: Fungicides to prevent and cure apple rot disease" 36% Osthole·Carbendazim suspension is designed to prevent apple rot disease Field efficacy test.

[0064] 2.1.1 Test agents

[0065] 1% Osthole water emulsion 200 times. (Provided by Jiangsu Academy of Agricultural Sciences)

[0066] 50% carbendazim suspension 500 times. (Provided by Jiangsu Taicang Pesticide Factory)

[0067] 36% Osthole·Carbendazim Suspension Concentrate 400, 500, 600 times. (Prepared by Yantai Academy of Agricultural Sciences)

[0068] 2.1.2 Control agent

[0069] 10% Shigao water dispe...

Embodiment 3

[0083] Safety test

[0084] The content of carbendazim in the compound composition is 15% less than that of the commercially available products, so its toxicity to humans and animals and safety to crops are in line with the requirements; the content of osthole in the compound composition is 1%. The toxicity test results of accredited institutions show that 1% Osthole Water Emulsion is a slightly toxic pesticide:

[0085] Acute oral toxicity LD50 in rats >5000mg / kg, ♀>5000mg / kg;

[0086] Acute dermal toxicity in rats LD50 >5000mg / kg, ♀>5000mg / kg;

[0087] Rabbit eye irritation score is 0 (1h), after 48h, it is 0 (1:100) dilution, no irritation to eyes;

[0088] The rabbit eye irritation score is 0 (4h), which is non-irritating to the skin.

Abstract

The invention discloses application of compositional composition of osthole and cardendazim in the field of agriculture, specifically aims at applied research of preventing and treating ring rot of apple.The present invention provides application of osthole and compositional composition of osthole and cardendazim in the field of agriculture, the weight ratio of osthole and cardendazim in the compositional composition is 1:25-40 with a preferable proportion of 1:30-40 and an optimum proportion of 1:35.The compositional composition of osthole and cardendazim is distinguished in the respect of preventing and treating ring rot of apple.

Description

1. Technical Field [0001] The invention relates to osthol and its compound composition, in particular to the compound composition of osthole and carbendazim, which is used as a fungicide to prevent and treat apple ring disease, and belongs to the technical field of compound composition of fungicides. 2. Background technology [0002] Apple ring disease is a widespread and severe disease in apple orchards that can cause a large number of rotten fruits. Ring disease began to occur in August and continued to increase before harvest. The rotten fruit rate is generally 20-50%, and the severe ones can reach 70-90%, which directly affects the economic income of fruit farmers. [0003] The coumarin compound Osthole is a plant-derived pesticide with a chemical name of 8-(3-methyl-2-butenyl) methyl ether ketone, which is derived from the Umbelliferae plant Cnidium monnieri (L .) Cuss) plant extracts are also present in the roots and rhizomes of imperator, angelica, angelica, and celery. Th...
