Embodiment 1

[0066] A method of utilizing oleanane-type pentacyclic triterpene compounds to prevent and treat bacterial diseases of crops, the steps are as follows:

[0067] Weigh compound I, and prepare 1.0 and 2.0 g / L solutions with distilled water, respectively. Potato seed potatoes were cut into 3-4 cm square blocks, respectively soaked in two concentrations of compound I solutions, taken out after 1 minute, and placed on the ground to naturally dry for 2 hours. The chemical pesticide control test group soaked potato seed pieces in 80% mancozeb wettable powder (concentration 0.8g / L) solution, took them out after 1 minute, and placed them on the ground for 2 hours naturally. In the clean water control group, potato seed pieces were soaked in distilled water, and the other treatments were the same.

[0068] The potato seed pieces treated above were sown in the test field. Apply decomposed organic fertilizer (15000kg / hm 2 ) as basal fertilizer, 300kg / hm of compound fertilizer is applie...

Embodiment 2

[0074] A method of utilizing oleanane-type pentacyclic triterpene compounds to prevent and treat bacterial diseases of crops, the steps are as follows:

[0075] Take the mixture of compound I and compound II (1:1), and prepare 0.5, 1.0 and 2.0 g / L solutions with distilled water, respectively, and set aside.

[0076] Tomato seeds were sown in seedling trays, and the seedling substrate was peat and vermiculite (ratio: 2:1). When the tomato seedlings reached 3-5 leaves, the tomato seedlings were taken out and transplanted in the test field. Organic fertilizers and compound fertilizers were applied to the test field, and the conventional management was carried out. One day after transplanting, the tomato seedlings were sprayed with compound I and compound II solutions at concentrations of 0.5, 1.0 and 2.0 g / L, respectively. In the chemical pesticide control group, 80% mancozeb wettable powder was used to prepare a solution with a concentration of 1.3 g / L to spray tomato seedling...

Embodiment 3

[0084] A method of utilizing oleanane-type pentacyclic triterpene compounds to prevent and treat bacterial diseases of crops, the steps are as follows:

[0085] Compound Ⅲ is extracted from the seeds of the traditional Chinese medicine Kochia chinensis, and mainly contains three chemical substances. The first substance: R 1 for OH, R 2 for CH 3 , R 3 for CH 3 ;Second substance: R 1 for OH, R 2 for CH 2 OH,R 3 for CH 3 ;Third substance: R 1 for OH, R 2 for CH 2 OH,R 3 for COOCH 3 . Compound III was prepared into a 1.0 g / L solution with distilled water.

[0086] Tomato seeds were sown in seedling trays, and the seedling substrate was peat and vermiculite (ratio: 2:1). When the tomato seedlings reach 3 to 5 leaves, take out the tomato seedlings, remove the soil from the roots as much as possible, and use the following two methods for treatment:

[0087] (1) Root soaking treatment. The tomato seedling roots were immersed in the compound III solution (concentration...

Abstract

The invention relates to an application of an oleanane-type pentacyclic triterpene compound in preventing and treating bacterial diseases of agricultural crops and a method for preventing and treating bacterial diseases of agricultural crops using the oleanane-type pentacyclic triterpene compound. The present invention does not utilize the direct bacteriostasis of oleane-type pentacyclic triterpenoids, but improves the resistance of crops to bacterial diseases by soaking seeds before sowing or soaking roots before transplanting or spraying leaves after transplanting ability, and ultimately achieve the purpose of disease resistance. More importantly, the prevention and control method provided by the present invention only needs to be used once before planting to achieve the purpose of alleviating bacterial diseases, which greatly reduces the control cost of conventional pesticides.

Description

technical field [0001] The invention belongs to the technical field of plant protection, in particular to the application and method of an oleanane-type pentacyclic triterpene compound in preventing and treating bacterial diseases of crops. Background technique [0002] Oleanane type, also known as β-balm resin type, belongs to pentacyclic triterpenoids. These compounds are widely distributed in the plant kingdom, and mainly exist in free or saponin-bound states. Most of the structures of this type of compounds contain C 3 -β-OH, the A / B, B / C, and C / D rings in the five six-membered rings are all trans, and most of the D / E rings are in cis arrangement. Saponin compounds containing pentacyclic triterpene core have a wide range of pharmacological effects and important biological activities, such as anti-inflammation, liver protection, anti-virus, anti-tumor, anti-hypertension, anti-atherosclerosis, anti-arrhythmia and lipid-lowering , hypoglycemic and other effects, has attr...
