The invention provides pesticide residue detection equipment which comprises an equipment box, a first fixed disc, a second fixed disc, a sampling bottle, a cooling device, a detection device and a weighing device, a second ball is arranged on the equipment box in a rolling mode and abuts against the second fixing disc. A rotating shaft of the motor is connected with the second fixed disc; the detection device is arranged on a first sliding plate and is positioned in the equipment box; the weighing device is arranged on a second sliding plate and is positioned in the equipment box; a sliding strip is arranged on the equipment box in a sliding manner and is connected with a reagent fixing plate; the cooling device is arranged in the equipment box and is in control connection with a refrigeration sheet; a turntable is rotationally arranged on a fixed column, and the first ball is arranged on the first fixed disc in a rolling manner and abuts against the turntable; a telescopic rod on thecylinder is connected with the turntable; and the sampling bottle is arranged on the second fixed disc in a sliding manner and abuts against the first fixed disc. Pesticide residues on the surface ofan object to be detected are rapidly mixed with distilled water, fruits and vegetables to be sampled are not prone to breakage, the detection result is more accurate, multiple products are sampled and detected at the same time, the detection speed is high, and the efficiency is high.

The invention provides a production and preparation method of a pesticide residue removal agent. The production and preparation method comprises the steps that a silicon oxide sol water solution is pre-formed, a silver-containing titanium oxide precursor solution is added into the silicon oxide sol water solution, thus the hydrolysis process of a titanium oxide precursor and generation of titaniumoxide particles are limited by a silicon oxide sol network, and overgrowth of the titanium oxide particles is controlled accordingly. The particle size of prepared nanometer titanium dioxide is smaller than 3 nm, the catalytic activity is high, and dispersion is stable. Ferric oxide nanoparticles are introduced into the preparation process to form a complex with titanium dioxide particles, the reaction catalytic activity is enhanced, and parts of reaction products can be flocculated and precipitated and thus are conveniently removed.

The invention relates to an agricultural sterilization composite compounded by tiadinil and thifluzamide, an agricultural bactericide comprising the sterilization composite, and an application of the sterilization composite in controlling a rice sheath blight disease and rice blast. The agricultural sterilization composite lowers application cost, reduces environmental pollution and pesticide residue, has no obvious adverse effect on test crops, is good in safety, meets safety requirements on pesticide preparations, can be used for disease control of various crops, and has a good control effect on the rice sheath blight disease and the rice blast particularly; the lasting period of the sterilization composite is prolonged; and leaf colors, growth and the like are normal.

The invention relates to an insecticide-fertilizer for an out-of-season fruit green radish and a preparation method thereof. The insecticide-fertilizer is a high-concentration clear solution water-soluble Insecticide-fertilizer prepared by mixing a macroelement water-soluble fertilizer and a biopesticide. The insecticide-fertilizer comprises the following active ingredients in parts by weight: 14.29 parts of ammonium polyphosphate, 8.93 parts of potassium nitrate, 4.29 parts of phosphoric acid, 22.14 parts of potassium tripolyphosphate, 0.29 parts of zinc sulphate monohydrate, 0.43 parts of boric acid, 4.2 parts of sorbitol, 2.5 parts of mannite, 2.4 parts of xylitol, 2.2 parts of glycerin, 5.26 parts of sulphur submicron powder, 1.21 parts of allicin, 0.18 parts of mandala dry powder, 3.68 parts of plantain herb, 1.53 parts of pepper and 100 parts of softened water. The insecticide-fertilizer can be used for effectively promoting the expansion of a radish fleshy root and inhibiting the plant diseases and insect pests; particularly the prevention effective rate for the soft rot is 100% and the pesticide residue is zreo.

The invention discloses an environment-friendly pesticide for paddy. The pesticide is prepared from the following raw materials in parts by weight: 15-20 parts of coptis chinensis, 15-20 parts of dandelion, 10-15 parts of cortex pseudolaricis, 10-15 parts of aloe, 5-10 parts of radix phytolaccae, 5-10 parts of acorus calamus, 5-8 parts of cloves, 5-8 parts of fructus forsythiae, 3-5 parts of radix sophorae flavescentis and 0.1-0.3 part of synergist. According to the preparation method, a large amount of water is used as a solvent, and traditional Chinese medicinal materials are used as medicinal ingredients, so that the environment-friendly pesticide is safe and environment-friendly and is an inevitable trend of pesticide preparations in the 21st century; and the components are harmonized with the synergist, so that the synergistic effect of the pesticide can be greatly improved under a condition that the dosage of the pesticide is not increased, the cost is saved, the pesticide effect is improved, pesticide residues are reduced, and the environment is effectively protected.

The invention discloses a chimonanthus nitens disease prevention liquid and an application method thereof. The chimonanthus nitens disease prevention liquid is prepared from, by weight, 40-60 parts ofchimonanthus nitens bark or stems, 15-25 parts of garlic, 18-22 parts of ginger, 16-24 parts of rock candy and a plurality of parts of water. The chimonanthus nitens disease prevention liquid of theinvention is safe to human and livestock, and has significant effect; after spraying with the chimonanthus nitens disease prevention liquid, the virus replication of tobacco plants infected with mosaic diseases and horse Y diseases is inhibited, leaves grow normally, chlorophyll is increased, photosynthesis is enhanced, leaf dry matter accumulation is increased, it is guaranteed that tobacco leaves grow mature, and no pesticide residues exist; and the chimonanthus nitens disease prevention liquid is suitable for all peasant households and units for tobacco planting and suitable for popularization.
