Problems solved by technology

[0009] At present, insecticides containing pymetrozine can only control insect pests, while fungicides containing epoxiconazole can only control diseases, but diseases and insect pests often occur in the field at the same time. In order to purchase insecticide products and fungicide products at the same time, mix them in the sprayer for spray control. Although this method can control diseases and insect pests better, the cost of control is high, and some fungicides and insecticides are due to chemical reactions and other reasons. It is not suitable for mixing and using together. Improper mixing can easily lead to problems such as decreased control effect

Embodiment 1

[0021] Example 1: 81% pymetrozine · epoxiconazole water dispersible granules

[0022] 80% pymetrozine, 1% epoxiconazole, 3.5% sodium dodecylbenzenesulfonate, 9.6% calcium lignosulfonate, 3% ammonium sulfate, 1.5% carboxymethylcellulose sodium, kaolin supplemented to 100% . Dry pulverize and knead the above formula in proportion, extrude and granulate, dry and sieve to obtain 81% pymetrozine·epiconazole water-dispersible granules.

Embodiment 2

[0023] Example 2: 81% pymetrozine · epoxiconazole water dispersible granules

[0024] 1% pymetrozine, 80% epoxiconazole, 4% sodium dodecylbenzenesulfonate, 8% calcium lignosulfonate, 1% sodium carboxymethylcellulose, 3% ammonium sulfate, kaolin to 100% . Dry pulverize the above formula according to the proportion, knead, extrude and granulate, dry and sieve to prepare 81% pymetrozine·epiconazole water dispersible granule.

Embodiment 3

[0025] Example 3: 55% pymetrozine·epiconazole water dispersible granules

[0026] 50% pymetrozine, 5% epoxiconazole, 4% sodium lauryl sulfate, 7% sodium alkylsulfonate, 3% ammonium sulfate, and light calcium carbonate make up to 100%. The above formula was dry crushed and kneaded according to the proportion, extruded and granulated, dried and sieved to prepare 55% pymetrozine·epiconazole water dispersible granules.

Abstract

An agricultural pesticidal and fungicidal combination containing pymetrozine and epoxiconazole consists of pymetrozine, epoxiconazole, auxiliary and excipient, the weight ratio of the pymetrozine to the epoxiconazole is 1:80 to 80:1, and according to percentage by weight, the content of each component in the combination is as follows: 1 to 80 percent of pymetrozine, 1 to 80 percent of epoxiconazole, 1 to 30 percent of auxiliary and the balance of excipient. The agricultural pesticidal and fungicidal combination can effectively control a variety of diseases and insect pests on paddy rice, wheat, peanut, banana and the like, solves the problem that the cost of simultaneously controlling insect pests and diseases is high, and has the advantages of broad control spectrum, slow resistance development, remarkable synergistic effect and low control cost.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticide and fungicide composition containing pymetrozine and epoxiconazole. Background technique [0002] Pymetrozine, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridinemethyleneamino)-1,2,4-3(2H)-one, chemical structure formula is : [0003] [0004] Pymetrozine has contact killing effect on pests, and also has systemic activity. It can be transported in xylem and phloem in plants, so it can be used as foliar spray or soil treatment. Thanks to its good transporting properties, new shoots and leaves can also be effectively protected after spraying the stems and leaves. Pymetrozine can be used to control most of the Homoptera pests, especially the Aphididae, Whitefly, Leafhopper and Planthopper pests. It is suitable for various field crops such as vegetables, rice, cotton, and fruit trees. [0005] Epoxiconazole, chemical name: (2RS,3SR)-3-(2-chlorophenyl)-2-(4-fluo...
