Problems solved by technology

[0004] The antiviral disease pesticides currently widely used in production are mostly single doses of morpholinidine hydrochloride, ribavirin, amino oligosaccharins or combined with zinc sulfate, or copper sulfate, or copper acetate, or Mixtures of cytokinins, etc., are all administered before the onset of the disease, the preventive effect is better, and the therapeutic effect is poor when administered after the onset of the disease

Embodiment 1

[0018] The formulation components of this embodiment are set as two-factor four-level orthogonal test, and the mass percentages of morpholine guanidine hydrochloride in the plant virus disease prevention and control agent are respectively 5%, 30%, 60%, 95%, amino oligosaccharin The mass percentages are respectively 0.2%, 1.0%, 4.0%, and 12%, and the rest is filler: potassium chloride.

[0019] Select a single dose of the above-mentioned components with a particle size between 0.01-0.99 mm, mix the above-mentioned components uniformly in proportion, and then process it into a soluble powder.

[0020] 1. Test materials and methods

[0021] The test medicament was prepared by the inventor of the patent of the present invention, and the test treatment was set as follows: 15 different component preparations of morpholinidine hydrochloride and amino oligosaccharin were combined, the contrast drug 2% amino oligosaccharin water agent (commercially available), 20% Morpholine guanidine...

Embodiment 230

[0040] Embodiment 230% morpholine guanidine+1% oligosaccharin soluble powder

[0041] Preparation components: morpholine hydrochloride 30.0%; amino oligosaccharin 1.0%; calcium chloride filler 69.0%.

[0042] Preparation method: crush the above-mentioned components to a particle size of 0.01-0.99mm, mix the above-mentioned components uniformly according to the above-mentioned proportions, and process them into soluble powders by airflow pulverization.

[0043] 1. Test materials and methods

[0044] The experimental site is located in Chenzhuang, Fan County, with good fertilizer and water conditions, convenient drainage and irrigation, and uniform soil fertility. The rice variety is Yujing 6, and the previous crop is wheat. The seedlings were transplanted on June 18, 2008, and planted with equal row spacing, the row spacing was 0.3 meters, the hole spacing was 0.12 meters, and the density was 18,000 clumps / mu. Other field managements were normal during the experiment.

Abstract

The invention relates to a medicament for preventing and controlling plant virus diseases, which comprises the following active ingredients in portion by weight: moroxydine hydrochloride 4.0-97.0, oligosaccharins 0.05-20.0 and soluble filler 2.0-96.0. The medicament for preventing and controlling the plant virus diseases of the invention uses the synergistic action of the moroxydine hydrochloride serving as an antiviral medicament and the oligosaccharins serving as a resistance-inducing agent to prevent and control the occurrence and development of crop virus diseases, has preventing and controlling functions, can achieve excellent preventing and controlling effect when used alone before or after the onset of the diseases and is long in medicament adaptation period, small in dosage and low in cost.

Description

technical field [0001] The invention relates to a pesticide, in particular to a plant virus disease control agent. Background technique [0002] Plant virus diseases are widely distributed, of various types, with wide transmission routes and serious harm. 716 species have been found, which can be divided into ssRNA, dsRNA, ssDNA, dsDNA, viroids, mimetic viruses, prions, satellite viruses, etc. Almost all cultivated plants suffer from at least one kind of virus damage, among the 209 recorded species Vegetables (excluding varieties) are infected with 195 kinds of viruses. Plant virus diseases are mainly transmitted semi-persistently and persistently through biological media such as aphids, cicadas, nematodes, fungi, mites, etc., and can also be transmitted through seeds, pollen, asexual propagules, humans, animals and agricultural farming measures. Competition, interfere with plant physiological metabolism, produce mosaic, necrosis, deformity and other symptoms, directly aff...
