Problems solved by technology

However, long-term use of carbendazim will cause gibberella to develop resistance to carbendazim, affecting the control effect
Moreover, carbendazim causes pesticide residues and causes environmental pollution
Single-agent control effects such as prochloraz and benzopropiconazole are poor and the cost is high
[0003] At present, there is a lack of a wheat scab control method that is harmless to human and animal health

Embodiment 1

[0031] The invention provides a method for preventing and treating wheat scab, comprising the steps of:

[0032] (1) preparing a selenium preparation solution; the selenium preparation is an inorganic state sodium selenate solution. Described inorganic state sodium selenate solution refers to the inorganic state sodium selenate solution that concentration is 5ppm. Spray clear water as a control group;

[0033] (2) In fine weather, the selenium preparation solution of above-mentioned concentration was sprayed with spraying equipment at the flowering stage of wheat for 2 times as a treatment group, and sprayed with clear water as a contrast;

[0034] (3) in the fine weather of 3 days after flowering, i.e. the initial stage of grouting, spray the selenium preparation solution 1 time on the treatment group with spray equipment;

[0035] (4) record processing group and clear water control group Gibberella spicule expansion speed in ear;

[0036] (5) record the sick spikelet rate...

Embodiment 2

[0045] The difference between embodiment 2 and embodiment 1 is:

[0046] The invention provides a method for preventing and treating wheat scab, comprising the steps of:

[0047] In step (1), the inorganic sodium selenate solution refers to the inorganic sodium selenate solution whose concentration is 30ppm. Spray clear water as a control group;

[0048] In step (2), in fine weather, the selenium preparation solution of above-mentioned concentration is sprayed 1 time with spraying equipment in the flowering stage of wheat as the treatment group, and sprayed with clear water as a contrast;

[0049] In step (3), in the fine weather of 4 days after flowering, i.e. the initial stage of grouting, spray the selenium preparation solution 2 times on the treatment group with spray equipment;

[0050] In step (5), record the sick spikelet rate of treatment group and clear water control group 24 days after anthesis, and described sick spikelet rate refers to the ratio of susceptible sp...

Embodiment 3

[0057] The invention provides a method for preventing and treating wheat scab, comprising the steps of:

[0058] In step (1), the selenium preparation is an inorganic sodium selenate solution. Described inorganic state sodium selenate solution refers to the inorganic state sodium selenate solution that concentration is 50ppm. Spray clear water as a control group;

[0059] In step (2), in fine weather, the selenium preparation solution of above-mentioned concentration is sprayed 3 times with spray equipment in the wheat flowering stage as treatment group, and spray clear water as contrast;

[0060] In step (3), in the fine weather of 5 days after flowering, i.e. the initial stage of grouting, spray the selenium preparation solution 1 time on the treatment group with spray equipment;

[0061] In step (5), record the sick spikelet rate of treatment group and clear water control group 25 days after anthesis.

[0062] In the present invention, under greenhouse conditions, the re...

Abstract

The invention discloses a wheat scab control method. The method includes 1, preparing selenium solution; 2, on a sunny day, spraying the selenium solution with the certain concentration on wheat in flowering period for 1 to 3 times through a spray device, allowing the wheat to serve as a treatment group, and spraying water on wheat serving as a control group; 3, on a sunny day for 3 to 5 days after flowering, namely in the early filling period, spraying the selenium solution on the treatment group through the spray device for 1 to 3 times, and spraying water on the control group; 4, recording the gibberella expanding speed on panicle portions of the treatment group and control group; 5, recording the diseased panicle rates of the treatment group and control group after 21 to 25 days after flowering; 6, recording grain infection rate after harvesting. The gibberella expanding speed on the panicle portions and the grain infection rate can be decreased significantly, and the wheat nutritional value can be increased and human, animal and plant health can be promoted through proper application.

Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to a method for preventing and treating wheat scab. Background technique [0002] Fusarium scab is one of the most important diseases on wheat. The prevalence of the disease not only causes a severe reduction in wheat yield, but also accumulates toxins in the grains, which can cause human and animal poisoning. Although there are many types of pesticides currently used to prevent and control wheat head blight, the active ingredients are mainly concentrated in carbendazim, prochloraz, triadimefon, tebuconazole, benzopropiconazole EC, cyclostrobin, etc. Several types of agents are usually sprayed with single or compound agents. Among them, carbendazim single agent or carbendazim compound agent is used more. Carbendazim cannot prevent the expansion of pathogenic bacteria, but it can effectively prevent the infection of pathogenic bacteria. However, long-term use of carbendazim...
