preparation example Construction

[0043] A preparation method of nematicide granules with sawdust as a carrier, comprising the following steps:

[0044] (1) Put the active ingredients into a homogenizer equipped with a solvent and a stabilizer to disperse evenly to obtain a mixed liquid with uniform viscosity;

[0045] (2) The prepared mixed liquid medicine is transferred to a high-level container;

[0046] (3) Put the sawdust into the mixer;

[0047] (4) Start the agitator, open the drain valve of the high-level container, and add the mixed liquid medicine;

[0048] (5) Check the effect of making granules by the adsorption method, and check the technical indicators of the products.

[0067] Embodiment 2 drug effect test

[0068] Adopt product of the present invention, do field efficacy test of tomato root-knot nematode, every processing repeats three times, every plot one repeats, adopts random block arrangement, plot area 20m 2 . Before sowing, lightly mix the soil with pesticides, and then sow. The number of root-knot nematodes was investigated 20 days and 40 days after the drug treatment. Adopt the diagonal sampling method, sample 3 plants at each point, investigate the disease index and the record standard of the incidence of root-knot nematode damage, and divide the disease into five grades according to the number of root-knot nematodes:

[0069] Level 0 no root knot;

[0070] Grade 1 root knot accounts for 1% to 25% of the whole root system;

[0071] Grade 2 Root knots account for 26% to 50% of the whole root system;

[0072] Grade 3 Root knots account for 51% to 75% of the whole root system;

[0073] Grade 4 Root knots account for 76% to 100% ...

Abstract

The invention relates to nematicide granules with sawdust as a carrier and a preparation method thereof. The granules comprise the following components in percentage by weight: 1-30 percent of active ingredient, 2-30 percent of stabilizer, 5-20 percent of solvent and 60-80 percent of sawdust, wherein the active ingredient is one or more of fosthiazate, abamectin, verticillium chlamydosporium, paecilomyces lilacinus and the like. The granules have the advantages of large adsorption capacity, long acting time, capability of improving soil conditions, rich sawdust rich, no limitation to resource and high convenience in use.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a nematicide granule with sawdust as a carrier and a preparation method thereof. Background technique [0002] Root-knot nematodes mainly damage the roots of various vegetables, showing more lateral roots and fibrous roots than normal, and forming spherical or conical white nodules of various sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground part of the damaged plant grows short and slow, with abnormal leaf color, few fruits, low yield, and even premature death of the plant. The nematodes currently known to damage vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Nematodes have a wide range of hosts and often damage more than 30 kinds of vegetables such as melons, solanaceous fruits, beans, radishes, carrots, lettuce, and cabbage, and can also spread ...
