Special disease-preventing composition for paddy rice

Abstract

The invention relates to a special disease-preventing composition for paddy rice, which is prepared from the following materials in parts by weight: 1 to 5 parts of pyrethrum extract, 1 to 3 parts ofallicin and 1 to 3 parts of methylisothiazolinone. By preparing the disease-preventing composition for paddy rice from the pyrethrum extract, allicin and methylisothiazolinone and adding the special disease-preventing composition for paddy rice into an ecological fertilizer for paddy rice growing, and the ecological fertilizer can remarkably reduce the incidence of diseases, such as yellow rice borer disease, leaf folder disease and rice false smut, when applied to paddy rice growing, thus remarkably increasing the acre yield of paddy rice fields.

Description

technical field [0001] The invention belongs to the field of agricultural planting fertilizers, in particular to a special disease-preventing composition for rice. Background technique [0002] The macronutrients nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth, and fertilizers containing nitrogen, phosphorus, and potassium need to be used to make up for it. In the micronutrient elements, except chlorine, which is not lacking in the soil, other nutrients need to be applied with trace element fertilizers. Fertilizers are generally mostly inorganic compounds, and only urea is an organic compound. Any chemical fertilizer that contains only one nutrient element that can indicate the content is called a unit fertilizer, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc. Any chemical fertilizer that contains two or more of the three nutritional elements nitrogen, phosphorus, and potassium and whose content c...
