Embodiment 1

[0037] 1. Experimental medicine and other materials

[0038] Preparation of carvacrol solution: Carvacrol was purchased from sigma (carvacrol, article number: W224511-100G-K, CAS number: 499-75-2), and 250 mg of carvacrol original drug was weighed with an electronic balance, and 1000 μL of koji was measured. Laton, 500 μL ethanol, and 3% Tween-20 solution were used to dissolve to 10 mL to obtain a 25 mg / mL carvacrol solution.

[0039] 10% thiazophosphine granules were purchased from the Pesticide Factory of the Institute of Plant Protection, Chinese Academy of Agricultural Sciences.

[0040] In this experiment, tomato seedlings were taken as an example. The variety of tomato was Hard Fen No. 8, which was purchased from the National Vegetable Engineering Technology Research Center.

[0041] 2. Experimental method

[0042] The experiment was divided into nine groups, as follows:

[0043] (1) CK group: no medicine was added;

[0044] (2) 2mg thiazophosphine group: Sprinkle in...

Embodiment 2

[0060] Based on the above results, we also investigated the dosage ratio range of carvacrol and thiazophosphine.

[0061] The results show that when using thiazophosphine, combined use of carvacrol can significantly reduce the inhibitory effect of thiazophosphine on plants; Ratio (carvacrol: thiazole phosphine = 1:500) can show the above effects.

[0062] It should be noted that the above data only represent the results of the direct experimental verification of the present invention, and are not used to limit the ratio of carvacrol and thiazophosphine. Those skilled in the art can reasonably predict the excess of carvacrol based on the results of the present invention: Thiazophosphine=1: (0.001-500) The scheme of this ratio range should also show the same or similar efficacy.

Embodiment 3

[0064] In embodiment 1, carvacrol is replaced by following five kinds of substances respectively: (1) p-mentan-2-alcohol, (2) 2-methyl-4-isopropyl phenol, (3) 4-methyl -2-isopropylphenol, (4) 3-methyl-4-isopropylphenol, (5) 4-methyl-3-isopropylphenol.

Abstract

The invention discloses the application of carvacrol and its derivatives and analogues in eliminating or reducing thiazophosphine injury. The research of the present invention shows that the mixed use of carvacrol and thiazole phosphine can eliminate / reduce the inhibitory effect of thiazolyl phosphine on plant growth, and will not affect the control effect of thiazolyl phosphine on plant pests, and at the same time, the inhibitory effect on plant pests is also strengthened. Therefore, the combination of carvacrol and thiazophosphine can be used to develop new medicaments for preventing and controlling plant pests (such as plant nematodes), which will not affect the growth of plants while effectively preventing and controlling plant pests and diseases. Moreover, carvacrol widely exists in spice plants such as thyme, oregano, and winter savory. As a plant-derived component, it is environmentally friendly and safe. Therefore, the scheme of the present invention has important theoretical guiding significance and practical application value for the prevention and treatment of plant diseases.

Description

technical field [0001] The invention belongs to the field of agricultural technology. More specifically, it relates to the application of carvacrol and its derivatives and analogs in eliminating or reducing thiazophosphine injury. Background technique [0002] Thiazophosphine is an organophosphorus pesticide, and its mechanism of action is to inhibit the action of the target organism, acetylcholinesterase, so as to achieve the effect of preventing and controlling harmful organisms such as root-knot nematodes. Especially as a nematicide, it is widely used. Plant parasitic nematodes are important plant pathogens. According to reports, the economic value of crops caused by plant nematode damage is more than 100 billion U.S. dollars every year in the world. The plant nematode species that cause the greatest losses to crops mainly include root-knot nematodes (Meloidogyne spp.), cyst nematodes (Heterodera spp.), spherical cyst nematodes (Globodera spp.), short-body nematodes (P...
