Problems solved by technology

[0004] Traditional fungicides are mostly chemical agents. This kind of fungicide is only compounded by chemical agents. Although the bactericidal effect is fast, the environmental pollution is serious, and the soil residue is large, which endangers the health of humans and animals.

Embodiment 1

[0019] A fungicide composition, consisting of the active ingredient prochloraz and a plant extract, the weight ratio of phenoxystrobin and the plant extract is 1:12, and the plant extracts are the cane extract of nightflower and hibiscus stem bark The mixture of extract, zedoary stem bark extract, and Toosendan fruit extract, the weight ratio of the night cross cane extract: hibiscus stem bark extract: zedoary stem bark extract: toosendan fruit extract is 1.5:1:1.5:5.

[0020] Wherein, plant extract adopts following method to prepare:

[0021] 1) Take the cane of night cross, stem bark of hibiscus, stem bark of curcuma, and toosendan fruit, wash them separately, dry them in the air at a temperature of 40-60°C until the water content is 15-30%, and crush them with a grinder , through a 40-mesh sieve, and set aside;

[0022] 2) Add 10-30 times the amount of acetone to the crushed cane, hibiscus stem bark, curcuma stem bark, and toosendan fruit, place them on a shaker for 24 ho...

Embodiment 2

[0026] A fungicide composition, consisting of the active ingredient prochloraz and a plant extract, the weight ratio of fenoxystrobin and the plant extract is 1:2, and the plant extracts are the extract of the cane of night cross and the stem bark of hibiscus The mixture of extract, zedoary stem bark extract, and Toosendan fruit extract, the weight ratio of the night cross cane extract: hibiscus stem bark extract: zedoary stem bark extract: toosendan fruit extract is 0.5:2:1:6.

[0027] Wherein, the preparation method of the plant extract is the same as in Example 1.

Embodiment 3

[0029] A fungicide composition, consisting of the active ingredient prochloraz and a plant extract, the weight ratio of fenoxystrobin and the plant extract is 1:16, and the plant extracts are the cane extract of night cross and hibiscus stem bark The mixture of extract, zedoary stem bark extract, and Toosendan fruit extract, the weight ratio of the night cross cane extract: hibiscus stem bark extract: zedoary stem bark extract: toosendan fruit extract is 3:1:2:4.

[0030] Wherein, the preparation method of the plant extract is the same as in Example 1.

Abstract

The invention discloses a bactericide composition. The effective components of the bactericide composition include prochloraz and a plant extract, the weight ratio of the prochloraz to the plant extract is 1:2-16, the plant extract is the mixture of a tuber fleeceflower stem extract, a pseudolarix amabilis bark extract, a curcuma zedoary bark extract and a szechwan Chinaberry fruit extract, and the weight ratio of the tuber fleeceflower stem extract to the pseudolarix amabilis bark extract to the curcuma zedoary bark extract to the szechwan Chinaberry fruit extract is 0.5-3:1-2:1-2:4-6. The prochloraz and the plant extract are compounded to ensure that the activity of the composition is more remarkable than that of prochloraz used alone, the bactericidal effect is good, the effect is fast, and the prevention and control effect is more lasting. In addition, the bactericide composition is safe to crops, stable in chemical property and safe, the environmental destruction brought by a chemical pesticide is reduced, and residual harmful ingredients of soil are decreased.

Description

technical field [0001] The invention belongs to the technical field of fungicides, and in particular relates to a fungicide composition. Background technique [0002] For a long time, chemical pesticides have been monopolized in plant protection because of their high efficiency, quick effect, low cost and convenient use. As people pay more and more attention to health and environmental issues, chemical pesticides have been questioned because of their residues and environmental pollution. Especially for foods that directly affect people's health, countries around the world have implemented "green trade barriers" to limit the amount of chemical pesticide residues. Therefore, reducing the use of chemical pesticides and finding alternative chemical pesticides for disease control has become the focus of future research. [0003] Prochloraz Prochloraz is a broad-spectrum fungicide that has obvious control effects on various crop diseases caused by Ascomycetes and Deuteromycetes....
