Embodiment 1

[0027] Carrier Screening: Activated clay and bentonite were selected as carriers respectively, and their wettability and suspension properties were measured after ultrasonic pulverization. The results are shown in Tables 1 and 2.

[0028] Table 1 Wettability of different carriers

[0029]

[0030] Table 2 Suspension properties of different carriers

[0031]

[0032] It can be seen from the data in the table that the carrier bentonite has short wetting time and high suspension rate, so bentonite is selected as the carrier.

Embodiment 2

[0034] Screening of wetting agents: Sodium dodecylbenzenesulfonate and Tween 60 were respectively selected as wetting agents, and their wettability and suspending properties were measured after ultrasonic pulverization. The results are shown in Table 3 and 4.

[0035] Table 3 Wettability of different wetting agents

[0036]

[0037] Table 4 Suspension of different wetting agents

[0038] D

[0039] It can be seen from the data in the table that there is no significant difference in wettability between sodium dodecylbenzenesulfonate and Tween 60, but Tween 60 is liquid at room temperature and will solidify when the temperature is too low, so it is not easy to mix with powder. Therefore, it is better to choose sodium dodecylbenzenesulfonate as the wetting agent.

Embodiment 3

[0041] Dispersant screening: choose sodium lignosulfonate and calcium lignosulfonate as dispersants respectively, after ultrasonic pulverization, measure their suspending properties respectively. The results are shown in Table 5.

[0042] Table 5 Suspension of different dispersants

[0043] Dispersant

[0044] In conjunction with the data in the table, the best dispersant screened by the present invention is calcium lignosulfonate.

Abstract

The invention discloses a wettable powder capable of preventing and treating fruit and vegetable brown rot and aphid as well as a preparation method thereof. The wettable powder comprises the components by weight: 20-30% of active components, 55-60% of carrier, 7-13% of wetting agent and 2-7% of dispersant; wherein the active components are a Szechwan chinaberry fruit extract product and berberine. The preparation method comprises the following steps: 1)mixing the Szechwan chinaberry fruit extract product and berberine in proportion, performing ultramicro-pulverization, passing through a sieve with 325 meshes to obtain the active components; 2)mixing the active components with a carrier, a wetting agent and a dispersant in proportion, performing ultramicro-pulverization, collecting powder after ultramicro-pulverization, performing spray drying, passing through the sieve with 325 meshes, and repeatedly operating until all the powder is passed through the sieve with 325 meshes to obtain the wettable powder. The wettable powder is capable of strongly inhibiting fruit and vegetable brown rot and aphid, and has the advantages of no toxicity, no pesticide residue, environmental protection, stabilization, high efficiency and low cost.

Description

technical field [0001] The invention relates to a wettable powder for preventing and treating fruit and vegetable brown rot and aphids and a preparation method thereof. Background technique [0002] The widespread use of chemical pesticides has played a huge role in ensuring high and stable crop yields. However, the "3R" problem caused by the long-term and large-scale unreasonable use of traditional chemical pesticides, that is, the residue, resistance, and rampantness is becoming more and more serious, which has aroused widespread concern in the society. It is more and more urgent to seek and develop new pesticides that are safe for human health and ecological environment. Compared with chemical pesticides, biological pesticides are generally considered to have obvious advantages such as no pollution, no pollution, no residue, and less resistance. [0003] Brown rot, also known as fruit rot, is a kind of sclerotinia, which is distributed in both north and south of China. ...
