Embodiment 1

[0021] Example 1 The effect of the composition containing flubendiamide and plant-derived substances on beet armyworm

[0022] Beet armyworm collected in the field was used in the experiment, which was used for the experiment after two generations of breeding. The specific method is as follows:

[0023] Leaf disc preparation: select clean bracts, wash and dry them, and use a puncher to make leaf discs for later use.

[0024] Before the drug preparation test, different concentration gradients were prepared according to different proportioning schemes, with 6 concentrations for each proportioning.

[0025] Dipping: Use tweezers to pick up the leaf discs and dip them in the liquid medicine for 5 seconds, take them out and dry them on absorbent paper, and put them in a 24-well plate after air-drying naturally, with 2 pieces per well. A total of 3 plates were placed for each concentration treatment.

[0026] Inoculation: Put one 3rd instar larva of beet armyworm in each well of ...

Embodiment 2

[0038] Example 2 The effect of the composition containing flubendiamide and plant-derived substances on the rice leaf roller

[0039] According to the protocol, compound formulations and single doses were prepared, and activity pre-tests were carried out. According to the results of the preliminary test, the preparation is formulated into the required concentration. Before the experiment, plots were set up, listed, and the base number of rice leaf rollers were investigated, and corresponding single doses and blank controls were set up, and conventional constant sprays were used with hand-held sprayers. 7 days after spraying, the effect of pesticides on rice leaf roller was investigated. Convert percentages to efficacy using Abbot's formula.

Embodiment 3

[0047] Example 3 The effect of the composition containing flubendiamide and plant-derived substances on apple pests

[0048] According to the protocol, compound formulations and single doses were prepared, and activity pre-tests were carried out. According to the pre-test of activity determination, the preparation is formulated into the required concentration. Before the test, set up plots, list, investigate the base of apple leaf tortrix, and set up corresponding single doses and blank controls, and use a hand-held sprayer to spray conventionally. 3d survey on the effect of pesticides on apple leaf tortrix after treatment. Carry out calculation and statistics according to the formula of embodiment 2, the results are shown in Table 3.

Abstract

The invention relates to an agricultural composition containing flubendiamide and plant-derived substances, and belongs to the field of plant protection, wherein the plant-derived substances are active components of one or a plurality of materials selected from plant alkaloids, plant terpenes, plant flavones and plant light-activated toxins, a mass part ratio of A to B is 30:1-1:30, and the composition has significant plant diseases and insect pest prevention effects on crops.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to an agricultural composition containing flubendiamide and plant-derived substances and its application. The composition of the invention can effectively prevent and control crop diseases and insect pests. Background technique [0002] In recent years, due to single and unscientific use of pesticides, pests and diseases have developed resistance to varying degrees, while agricultural and forestry production still uses chemical pesticides as the main control species, causing serious environmental pollution and ecological environment. With the improvement of people's living standards and the enhancement of health awareness, the research and development of biological pesticides has gradually attracted the attention of pesticide research and development workers, and has become a hot spot for the sustainable development of agriculture and forestry. It is to improve the environ...
