Abstract
A bromothalonil water dispersible granule and a preparation method thereof and belongs to the technical field of pesticides. The bromothalonil water dispersible granule comprises the following components in percentage by weight: 30%-70% of bromothalonil, 1%-15% of a dispersing agent, 1%-15% of a wetting agent, 1%-15% of a binder, 1%-15% of a stabilizer, 1%-15% of a disintegrating agent, 1%-5% of a penetrating agent and the rest of packing. The preparation method comprises the steps of: firstly uniformly mixing the bromothalonil with the dispersing agent, the wetting agent, the binder, the stabilizer, the disintegrating agent, the penetrating agent and the packing, and carrying out air powder processing; then watering and kneading; and finally pelleting and drying. The bromothalonil water dispersible granule has powerful internal absorption and seepage force and can kill pathogenic bacteria intruding into plant bodies; the good effect can be achieved by using the low-concentration bromothalonil water dispersible granule; and the bromothalonil water dispersible granule has the quick-acting and persistent effects and the long-term advantageous effect can be kept.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicide water-dispersible granule and a preparation method thereof. Background technique [0002] Bromothalonil is a broad-spectrum, high-efficiency, low-toxicity fungicide with a chemical formula of C6H6Br2N2 and a molecular weight of 265.94. Bromothalonil can inhibit and eradicate the growth of fungi, bacteria, and algae, and has a good control effect on crop diseases, and has special effects on anthracnose. Widely applicable to fruit trees, grapes, vegetables, cotton, peanuts, watermelon, tobacco, tea trees, flowers and other crops, to prevent and control anthracnose, scab, scab, powdery mildew, rust, blight, damping-off, rhizome Rot, canker, bacterial wilt, angular spot and other fungal and bacterial diseases. The application method is flexible, and foliar spray, seed treatment and soil irrigation all show good control effects. [0003] At present, there...
