Embodiment 1

[0035] Example 1 61% Hemifluon·Hymexazol WP (60:1)

[0036] Phosphate 60%, hymexazol 1%, alkylbenzene sulfonate 6%, sodium lauryl sulfate 2%, white carbon black 6%, and diatomaceous earth make up 100%. According to the above formula ratio, the various materials were mixed and subjected to airflow milling to obtain 61% oxafluphos·hymexazol wettable powder.

Embodiment 2

[0037] Example 2 41% oxaflufos-oxaflucondone wettable powder (40:1)

[0038] Hexafluorophos 40%, oxaflucone 1%, sodium methylene bismethylnaphthalene sulfonate 7%, sodium lauryl sulfate 2%, and kaolin make up 100%. According to the above-mentioned formula ratio, the materials were mixed and air-flow pulverized to obtain 41% oxaflufos-oxafetocin wettable powder.

Embodiment 3

[0039] Example 3 31% hexafluoropyrimoxazole wettable powder (30:1)

[0040] Hexafluorophos 30%, pyridoxazole 1%, alkylbenzene sulfonate 8%, lignosulfonate 6%, white carbon black 10%, kaolin supplement 100%. According to the above formula ratio, the materials were mixed and air-flow pulverized to obtain 31% hexafluoro-pyridoxazole wettable powder.

Abstract

The invention provides a compound composition containing Dufulin and an oxazole bactericide, and a preparation thereof. The compound composition and the preparation are mainly used for controlling diseases of various crops. The compound composition comprises Dufulin and the oxazole bactericide, and a weight ratio of Dufulin to the oxazole bactericide is 60:1-1:30. The invention also provides the pesticide preparation of the compound composition containing Dufulin and the oxazole bactericide, and the compound composition accounts for 0.1-80% of the total weight of the pesticide preparation. The dosage form of the pesticide preparation can be a wettable powder, a water dispersible granule, an emulsion in water, a suspension or a seed coating agent as demanded. The compound composition has obvious synergistic effects in control of crop diseases in a certain ratio; and compared with single doses, the compound composition has the advantages of control spectrum enlargement, delaying of the drug resistance, obvious effect improvement, reduction of the use amount and application frequency of single doses, and protection of ecologic environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to compound compositions and preparations containing toxic fluorophosphorus and oxazole fungicides. Background technique [0002] As the climate and environment change, the types of plant diseases also change. The effect of a single pesticide variety on disease control is not ideal, and the resistance of the disease to a single pesticide variety is gradually increasing, and it is impossible to control multiple diseases at the same time. . For example, oxazole fungicides such as hymexazol, oxafefenone, pyridoxazole, oxafaxyl and other oxazole fungicides have been used for a long time, and the control effect on crop diseases will decrease. Hymexazol, oxafefenone, pyridoxazole, and oxadaxyl are all known and disclosed pesticide varieties in the art. [0003] Hymexazo: CAS No. 10004-44-1, chemical name is 3-hydroxy-5-methylisoxazole, hymexazo is a systemic fungicide and soil disinf...
