Embodiment 1
[0013] Embodiment 1: the preparation of pollution-free fungicide herbicide
[0014] The present invention provides a plant-derived nanometer slow-release pesticide composition of the fruit of the plant, which is characterized in that it is prepared from the following raw materials in parts by weight: 40-50 parts of the fruit, 10-20 parts of Eupatorium adenophorum, 10-20 parts of water, 20-25 parts of nano slow-release carrier;
[0015] The preparation method of described nano sustained-release carrier is:
[0016] (1) Mix silicon hydroxyapatite and attapulgite according to the mass ratio of 35-45: 10-15, add to the mixed solution of 230 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol, at 65 Stir at 60°C for 60 hours, filter, wash 3 times with hot ethanol at 60°C to remove excess dimethyl sulfoxide (DMSO), put it in a vacuum drying oven, dry at 60°C for 24 hours, grind and sieve to obtain a primary modification Complex;
[0017] (2) Mix 1 part of primary modif...
Embodiment 2
[0020] Embodiment 2: the test area is located in the potato test area of the farm, and the potatoes are made before, and the soil type is black soil, the soil organic matter content is 5.3%, and the pH value is 6.6; Spring fertilization; 175kg of phosphoric acid, 160kg of urea, and 125kg of potassium sulfate were applied per hectare.
[0021] There are 3 treatments in each test, 4 repetitions, each plot area is 10m2, and the test design is carried out according to a completely random design, wherein A: clear water blank control; B: compound carbendazim 800 times dilution positive control; C: this The 300-fold dilution of the botanical pesticide of the invention is used for seed dressing.
[0022] Survey content and data processing: 30 samples were randomly selected in each plot, investigated before the application of the drug and 30 days after sowing, recorded the number of diseased plants, and observed the emergence rate.
[0023] The test results show that the seedling em...
