Embodiment 1

[0026] The difference between this example and the control group is that the seed buds are sterilized before planting, and the seed buds are soaked in warm water at 38°C for 4 hours, then soaked in 500 times carbendazim with a concentration of 50% for 40 minutes, and finally washed with clean water 3 times, remove and dry. When preparing the soil, apply 50-60 kg per mu of quicklime powder with a particle size of 50 mesh, sprinkle it on the ground, cooperate with plowing the land, and fully mix it with the soil.

[0027] The number of cases and the amount of each pesticide residue are counted as shown in Table 2:

[0028]

[0029] It can be seen from Table 2 that in this embodiment, the incidence of various Scrophulariaceae scrophulariae can be significantly reduced by 3 times by disinfecting the seed buds before planting and disinfecting the soil during soil preparation. Therefore, the frequency of spraying pesticides is also reduced, and the amount of pesticide residues i...

Embodiment 2

[0031] The difference between this embodiment and the control group is: after spraying the pesticide for 3 days, spray 5 kg of hydrogen peroxide with a concentration of 8% per mu. Before spraying the pesticide for the first time, spread a layer of activated carbon evenly around the plant, and then spray the pesticide 5 times. Before the next spraying of pesticides, replace with a new layer of activated carbon.

[0032] The statistics of incidence times and pesticide residues are shown in Table 3:

[0033]

[0034] It can be seen from Table 3 that chemical degradation of pesticides by hydrogen peroxide and chemical adsorption of pesticides by activated carbon can significantly reduce the residual amount of pesticides.

Embodiment 3

[0036] A method for controlling plant diseases and insect pests of Scrophulariaceae, comprising the following steps:

[0037] 1) Disinfect the seed buds before planting, soak the seed buds with warm water at 35~40°C for 3~5 hours, then soak them in 50% carbendazim 500 times solution for 30min~50min, finally wash them with clean water, remove them and let them dry Dry;

[0038] 2) When preparing the soil, apply 50-60 kg per mu of quicklime powder with a particle size of 50 mesh, sprinkle it on the ground, cooperate with plowing the land, and fully mix with the soil;

[0039] 3) After the onset of leaf spot disease, spray 1500 times of thiophanate-methyl with a concentration of 70%. % trichlorfon 750 times liquid;

[0040] 4) After spraying pesticides for 3 days, spray 5 kg of hydrogen peroxide with a concentration of 8% per mu;

[0041] 5) Before spraying pesticides for the first time, spread a layer of activated carbon evenly around the plants, and after spraying pesticides...

Abstract

The invention discloses a scrophularia ningpoensis planting disease and pest control method for the purpose of solving the problems that in an existing scrophularia ningpoensis planting process, since a large quantity of pesticides are used, soil is polluted, and there are too many pesticide residues on scrophularia ningpoensis. The method comprises the first step of using carbendazim for disinfecting buds before planting, the second step of adding quick lime for disinfecting soil in the soil preparation process, the third step of spraying corresponding pesticides after pest and disease damage happens, the fourth step of spraying hydrogen peroxide with the concentration of 8% per mu three days after the pesticides are sprayed, and the fifth step of uniformly spreading a layer of activated carbon around plants before first time of pesticide spraying and changing a new layer of activated carbon before next time of pesticide spraying every five times of pesticide spraying. By the adoption of the method, the occurrence rate of pest and disease damage and the pesticide residues can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of planting Chinese medicinal materials, and in particular relates to a method for preventing and controlling planting diseases and insect pests of Scrophulariaceae. Background technique [0002] Scrophulariaceae is a perennial herb. Plant height 90cm ~ 160cm. The underground tuber is hypertrophic, conical or spindle-shaped, the lower part is often forked, and the outer skin is gray-yellow or gray-brown. Stems erect, quadrangular, grooved. The lower leaves are opposite, the upper leaves are sometimes alternate, short-stalked, ovate to ovate-elliptic, 7cm-20cm long, 3.5cm-12cm wide, apex pointed, base round or nearly truncate, margins finely serrated, leaves Dense hairs on back or tender stems. The cymes are scattered at the top, the total pedicel is 1cm-3cm long, the inflorescence axis and pedicel are covered with glandular hairs; the calyx is 2cm-3cm long, 5-lobed almost to the base, the lobes are nearly round, a...
