Embodiment 1

[0024] Example 1: 20% Cyanoxystrobin·Seconazole wettable powder

[0025] Cyanoxystrobin 4%, inoconazole 16%, NNO-11%, open powder 3%, sodium dodecylbenzene sulfonate 2%, attapulgite 30%, the rest is light calcium carbonate supplemented to 100 %. The above components are thoroughly mixed, pulverized by a sand mill and passed through a 300-mesh sieve to obtain 20% cyanostrobin·Seconazole wettable powder.

Embodiment 2

[0026] Example 2: 60% Cyanoxystrobin·Seconazole wettable powder

[0027] Cyanoxystrobin 40%, inoconazole 20%, NNO-11%, open powder 3%, sodium dodecylbenzene sulfonate 2%, attapulgite 30%, the rest is light calcium carbonate supplemented to 100 %. The above components are thoroughly mixed, crushed by a sand mill and sieved through a 300-mesh sieve to obtain 60% cyanostrobin·Seconazole wettable powder.

Embodiment 3

[0028] Example 3: 40% Cyanoxystrobin·Seconazole wettable powder

[0029] Cyanoxystrobin 20%, inoconazole 20%, NNO-11%, open powder 3%, sodium dodecylbenzene sulfonate 2%, attapulgite 30%, the rest is light calcium carbonate supplemented to 100 %. The above components are thoroughly mixed, crushed by a sand mill and sieved through a 300-mesh sieve to obtain 40% cyanostrobin·Seconazole wettable powder.

Abstract

The invention discloses a compound bactericide for controlling wheat scab and application thereof. The compound bactericide comprises phenamacril and ipconazole. A weight ratio of the phenamacril to the ipconazole is 1-40:40-1. The compound bactericide is synergic for inhibiting the growth of Gibberella zeae. The invention also discloses application of the compound bactericide in controlling wheat scab, the effect of controlling wheat scab can be significantly improved, the resistance of Gibberella zeae to the phenamacril can be delayed, wheat powdery mildew, rust disease and banded sclerotial blight are also treated, pesticide usage is greatly reduced, the cost is reduced, environmental pollution and pesticide residue are reduced, and the compound bactericide is environment friendly. The compound bactericide has important practical significance to the increase in social, economic and economic benefits.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a compound fungicide for preventing and treating wheat head blight and its application. Background technique [0002] Wheat is the most important cereal crop in the world and an important food crop in my country. Head blight, powdery mildew, sheath blight, rust and leaf blight are important fungal diseases that threaten wheat production and seriously affect the yield and quality of wheat. In particular, wheat head blight caused by Fusarium can not only cause devastating yield loss, but also produce large amounts of deoxynivalenol (DON) and zearalenol in the infected grain. Toxins such as Zearalenone seriously affect food security and threaten the health of humans and animals. [0003] Wheat head blight is an ascomycete disease of bud rot, seedling blight and ear rot / ear blight that can be caused by many kinds of Fusarium or Fusariumspp. Its pathogens include F. graminea...
