Wheat rust inhibitor and preparation method thereof

Abstract

The invention discloses a wheat rust inhibitor. The wheat rust inhibitor is prepared from raw materials in parts by weight as follows: 8-80 parts of a loss control regulating agent, 11-420 parts of mineral oil, 0.02-0.08 parts of nano-selenium, 50-100 parts of sodium carboxymethylcellulose and 399.92-930.98 parts of water, wherein the loss control regulating agent is prepared from aminated attapulgite and micro-nano biosilicon / carbon in the mass ratio being (3-5):(1-2) through mixing. The invention further discloses a preparation method of the wheat rust inhibitor. The wheat rust inhibitor and the preparation method have the advantages as follows: (1) preparation is simple, operation is simple and convenient, the cost is low, and large-scale production can be realized; (2) a nano-composite is prepared from the attapulgite, the mineral oil, nano-selenium, sodium carboxymethylcellulose and the like, can form a net-shaped nano-protective layer through self-assembly after being sprayed on wheat leaves and can effectively prevent invasion of pathogenic bacteria and reduce incidence; (3) the product is green, environment-friendly and safe and can reduce the infection rate of wheat rust by 65%-90%.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture, in particular to a wheat rust inhibitor and a preparation method thereof. Background technique [0002] Wheat rust is a major wheat disease with the most widespread area and the most serious damage in my country. In my country's northwest, southwest and Huanghuaihai wheat regions are the main epidemic areas of rust outbreaks. In epidemic years, wheat production can be reduced by more than 30%, and in severe years, the harvest may even be wiped out. Wheat rust is a strictly parasitic fungus. After infecting wheat, the fungus continues to produce a large number of spore piles. The large number of germ spores multiplying in a short period of time is the internal reason for the outbreak of wheat rust. [0003] At present, in addition to breeding disease-resistant varieties and carrying out autumn sowing and seed dressing, chemical control is still an effective measure to reduce the oc...

Problems solved by technology

For a long time, due to the large and single use of triadimefon, pathogenic bacteria quickly developed resistance to it

The long-term use of chemical reagents will not only have adverse effects on the environment, but the long-term single use of chemical pesticides will also have a great impact on the quality of its output
