Abstract
The invention belongs to the field of pesticides, and relates to a sterilization composition taking amino-oligosaccharide and thiophanate methyl as main active ingredient components, and a use method and application thereof. The composition comprises at least two active ingredients with dosage producing synergistic activity, and appropriate excipients, and is characterized in that the component I is the amino-oligosaccharide, and the component II is the thiophanate methyl. The ratio of weight parts of the amino-oligosaccharide and the thiophanate methyl is 20:1-1:50 in the invention. The preferred scheme is that the ratio of weight parts of the amino-oligosaccharide and the thiophanate methyl is 20:1-1:50. The composition and appropriate excipients are made into any agriculturally available formulation. The preferred formulation is a suspending agent, water dispersible granules and wettable powder. The use method of the invention is that the component I and the component II can be used for treating positions which produce diseases or disease danger in any order or simultaneously. The sterilization composition is used for controlling diseases of fruit, cereal, fruits, vegetables, beans, oil crops and ornamental crops and other crops.
Description
technical field [0001] The invention belongs to the field of pesticides, and relates to a bactericidal composition whose main active ingredients are amino-oligosaccharin and thiophanate-methyl, as well as its use method and application. Background technique [0002] The physical and chemical properties of thiophanate-methyl are as follows: [0003] Chemical name: 1,2-bis(3-methoxycarbonyl-2-thioureido)benzene [0004] English name: Thiophantate-Methyl [0005] CAS number: 23564-05-8 [0006] Structural formula: [0007] [0008] Molecular formula is C 12 h 14 N 4 o 4 S 2 , with a molecular weight of 342.4 [0009] Thiophanate-methyl belongs to the class of benzimidazoles, also known as thiophanate-methyl and formazol. It is a broad-spectrum systemic fungicide, which can prevent and treat various crop diseases, and has systemic, preventive and therapeutic effects. It is transformed into carbendazim in plants, which interferes with the formation of spindles in mit...
