CN103583199A - Control method for sitodiplosis mosellana of wheat - Google Patents

Abstract

The invention discloses a control method for sitodiplosis mosellana of wheat, and relates to the field of planting technologies for crops. The control method is characterized by comprising agricultural control and chemical control, and the chemical control further includes control in sowing periods, control in booting periods and control in heading periods. The control method has the advantages that steps are quite simple and can be easily understood; the method is quite clear and is suitable for profession planting personnel or common workers for reference and application, and pesticides and the like which are utilized in the control method are common efficient low-toxicity pesticides and are high in cost performance; the control method is reasonable, the sitodiplosis mosellana can be controlled conveniently, and an implementation effect is excellent.

Description

The method of preventing and treating of wheat midge

Technical field:

The present invention relates to proportion of crop planting technical field, be specifically related to a kind of method of preventing and treating of wheat midge.

Background technology:

Midge worm is a kind of insect, and adult health is little, and Exocarpium Citri Rubrum, orange or ginger-colored, slightly resembles mosquito, and feeler is elongated, and shape resembles string of Beads, has a pair of wing.Larva is flat avette, and color is identical with adult, inhales the juice in the crops such as wheat, broom corn millet, is pest.

And midge worm is the crushing insect on wheat.Change due to tillage and cultivation system; the reasons such as wheat breed renewal and traditional organochlorine insecticide forbidding; there is variation in the ecotope of midge worm existence, original Prevention Technique can not have been controlled its harm, and be not suitable with the requirement of current agricultural production and ecological protection.A series of unnecessary troubles have so just been brought.

Summary of the invention:

Technical problem to be solved by this invention is to overcome the method for preventing and treating that existing technological deficiency provides a kind of wheat midge that a kind of method is reasonable, control is convenient, implementation result is good.

Technical problem to be solved by this invention adopts following technical scheme to realize:

The method of preventing and treating of wheat midge, is characterized in that: comprises the following steps,

Step 1, cultural control: select pest-resistant cultivar, and assistant chemical control.With the plantation of the shift of crops such as cotton, rape, and postpone the management of spring one water, grow tiller and remove little tiller;

Step 2, chemical control:

2.1, control in sowing time: to the plot of harm occurs, take prior to seeding the method for spreading pesticide-clay mixture to prevent wholely.50% phoxim emulsifiable concentrate 200ml for mu during whole ground, adds water 5kg and mixes thoroughly and make pesticide-clay mixture and use, and Bian Sabian ploughs, and ploughs under in soil;

2.2, booting stage control: in late April, in time pesticide-clay mixture is spread fertilizer over the fields along wheat ridge, adopt 50% phoxim emulsifiable concentrate 200ml, add the medicament that water 5kg mixes thoroughly and spread fertilizer over the fields, suitably water little water after dispenser;

2.3, fringe phase control: concentrate spray medicine once before wheatland heading, spray once again when wheatland heading reaches 50%.Spray selection of time 6:00 in the afternoon, select beta-cypermethrin or phoxim pesticide.During heading flowering, every mu of use 80% DDT EC 100-150ml mixing carbendazim is watered spraying.

Beneficial effect of the present invention is: very simple, easy-to-understand of above-mentioned step, and very clear, be applicable to professional plant personnel or common staff's reference and use, and the agricultural chemicals using etc. is all common higher effective and lower toxic pesticide, cost performance is very high.The inventive method rationally, control is convenient, implementation result is good.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

The method of preventing and treating of wheat midge, is characterized in that: comprises the following steps,

Step 1, cultural control: select pest-resistant cultivar, and assistant chemical control.With the plantation of the shift of crops such as cotton, rape, and postpone the management of spring one water, grow tiller and remove little tiller;

Step 2, chemical control:

2.1, control in sowing time: to the plot of harm occurs, take prior to seeding the method for spreading pesticide-clay mixture to prevent wholely.50% phoxim emulsifiable concentrate 200ml for mu during whole ground, adds water 5kg and mixes thoroughly and make pesticide-clay mixture and use, and Bian Sabian ploughs, and ploughs under in soil;

2.2, booting stage control: in late April, in time pesticide-clay mixture is spread fertilizer over the fields along wheat ridge, adopt 50% phoxim emulsifiable concentrate 200ml, add the medicament that water 5kg mixes thoroughly and spread fertilizer over the fields, suitably water little water after dispenser;

2.3, fringe phase control: concentrate spray medicine once before wheatland heading, spray once again when wheatland heading reaches 50%.Spray selection of time 6:00 in the afternoon, select beta-cypermethrin or phoxim pesticide.During heading flowering, every mu of use 80% DDT EC 100-150ml mixing carbendazim is watered spraying.

More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
