Embodiment 1

[0024] The present embodiment utilizes the method that contains Trichoderma inoculum to reduce fresh corn Fusarium toxin, comprises the following steps:

[0025] 1) Treatment of fresh corn seeds: Before sowing, weigh 15-30 kilograms of corn seeds according to the required amount per hectare of land, and use Trichoderma-Bacillus seed coating agent in a mass ratio of 1:100 to the corn seeds. 200, sowing the corn seeds after coating;

[0026] 2) Treatment at the silking stage: During the silking stage of fresh corn, the whole plant is sprayed with 0.9-1.5 kg / ha of Trichoderma-Metarhizium anisopliae wettable powder;

[0027] 3) Treatment at the filling stage: during the filling stage of fresh corn, spray 1.5-1.8 kg / ha of Trichoderma-Metarhizium wettable powder on the ears of corn;

[0028] The Trichoderma strains are provided by the Trichoderma Strain Preservation and Management Center of Shanghai Jiaotong University, Trichoderma strains with broad-spectrum plant protection and b...

Embodiment 2

[0034] (1) Experimental point, corn variety

[0035] In Example 2, the experimental farm of Minhang Campus of Shanghai Jiaotong University was used as the experimental site, and the fresh corn variety was Jinfei.

[0036] (2) Test method:

[0037] Trichoderma GDSF1009-Bacillus amyloliquefaciens ACCC11060 coating treatment method: Before sowing, according to the ratio of drug species = 1:100 (W / W), pour Trichoderma-Bacillus seed coating agent powder into corn seeds, reconcile and mix uniform.

[0038] Trichoderma GDSF1009-Metarhizium anisopliae CY-1 wettable powder spray treatment method: during the corn silking period, apply 600 kg of potion per hectare, dissolve and dilute the Trichoderma-Metarhizium anisopliae wettable powder by 500 times with water, and use a sprayer to spray The whole corn plant is sprayed, and the liquid medicine should flow along the corn stalk to the base.

Abstract

The invention relates to a method for reducing fusarium toxins of fresh maize by using a trichoderma-containing fungicide. The method has an obvious inhibiting effect on fusarium toxin accumulation offresh maize, the decreasing amplitude of fumonisins (FB1) reaches 43.9%, and the decreasing amplitude of zearalenone (ZEN) reaches 100%. The method has the advantages of being environmentally friendly, capable of meeting the requirements of organic ecological green agriculture, good in persistence and easy to operate, and has an extremely wide application market.

Description

technical field [0001] The invention relates to the technical fields of plant protection biological control and food safety, and in particular relates to a method for reducing the toxin of Fusarium spp. Background technique [0002] Fresh corn is a field crop that is used as "vegetable, fruit, and grain". There are sweet corn, waxy corn, sweet waxy corn and other types. The fresh ear of sweet corn can be eaten raw or cooked, which is not only good in palatability, but also rich in nutrition; the ear of milk-ripened waxy corn and sweet waxy corn can be cooked and eaten directly, or the kernels can be frozen and used as vegetables. Used as food or fodder. In recent years, the fresh corn industry has shown a rapid development trend on a global scale. It is currently an emerging industry with the most competitive advantage and development potential. It is known as the "golden industry" in Europe, America and other regions. In China, fresh corn has an increase of more than 1,00...
