Description

A kind of corn borer method for integrated control

Technical field:

The present invention relates to proportion of crop planting technical field, be specifically related to a kind of corn borer method for integrated control.

Background technology:

Corn borer Pyrausta nubilalis (Hubern). be the Major Pests of corn.Mainly be distributed in the ground such as Beijing, northeast, Hebei, Henan, Sichuan, Guangxi.The spring of various places, summer, autumn sowing corn have damage to different degrees, especially the heaviest with Summer Maize.Corn borer, can send out harm milpa each position on the ground, and the part loss of function that makes to be injured, reduces grain yield.

And corn borer is a worldwide insect that danger is enormously potential, can there is 2-3 generation in year, and occurrence scope is large, and area is wide, and harm is heavy, to agricultural production, has brought great trouble.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency and provides that a kind of method is simple, step is clear, prevent and treat rational a kind of corn borer method for integrated control.

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

A method for integrated control, is characterized in that: comprises the following steps,

Step 1, cultural control:

1.1, select pest-resistant cultivar: select high resistance insect pest corn variety;

1.2, eliminate worm source: universal straw-returning technology, or by ensiling, the mode Treating straw such as make compost, eliminate worm source;

1.3, take Cultivation mode: between taking, mixed, interplanting form, alleviate corn borer to the causing harm of corn, as corn and peanut intercropping, interplanting corn soybean etc.;

1.4, artificial emasculation: in the corn borer serious area of causing harm, take out the male initial stage at corn, corn borer focuses mostly on and causes harm on the tassel of extracting out being about to.Artificial removal 2/3 tassel, takes out of and outside field, burns or buried, can eliminate a part of larva;

Step 2, physical control: in the adult emergence period, utilize the phototaxis of corn borer, adopt frequency ventilating type insecticidal lamp trapping, reduce the use of agricultural chemicals, to protect agroecological environment;

Step 3, chemical control:

3.1, the corn horn mouth initial stage, 3000 times of liquid of 2000 times of liquid of available Bt emulsion or abamectin emulsifiable concentrate are filled with the heart, and also available 5% phoxim granule thinks that horn mouth spreads fertilizer over the fields.Horn mouth is prevented and treated once latter stage again;

3.2, the fringe phase is with the 4.5% 2000 times of liquid spraying controls of cypermethrin or 48% Le Siben missible oil of making laughs, every mu of 30-60ml.

Beneficial effect of the present invention is: very simple of above-mentioned steps, and easy-to-understand, operate also very convenient, be applicable to specialty or non-professional plant personnel, and the cost of control is low, and the control cycle is short, be also applicable to fast preventing, by above-mentioned steps effectively and rapidly prevent disease, remove germ.The inventive method is simple, step is clear, control is reasonable.

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.

A method for integrated control, is characterized in that: comprises the following steps,

Step 1, cultural control:

1.1, select pest-resistant cultivar: select high resistance insect pest corn variety;

1.2, eliminate worm source: universal straw-returning technology, or by ensiling, the mode Treating straw such as make compost, eliminate worm source;

1.3, take Cultivation mode: between taking, mixed, interplanting form, alleviate corn borer to the causing harm of corn, as corn and peanut intercropping, interplanting corn soybean etc.;

1.4, artificial emasculation: in the corn borer serious area of causing harm, take out the male initial stage at corn, corn borer focuses mostly on and causes harm on the tassel of extracting out being about to.Artificial removal 2/3 tassel, takes out of and outside field, burns or buried, can eliminate a part of larva;

Step 2, physical control: in the adult emergence period, utilize the phototaxis of corn borer, adopt frequency ventilating type insecticidal lamp trapping, reduce the use of agricultural chemicals, to protect agroecological environment;

Step 3, chemical control:

3.1, the corn horn mouth initial stage, 3000 times of liquid of 2000 times of liquid of available Bt emulsion or abamectin emulsifiable concentrate are filled with the heart, and also available 5% phoxim granule thinks that horn mouth spreads fertilizer over the fields.Horn mouth is prevented and treated once latter stage again;

3.2, the fringe phase is with the 4.5% 2000 times of liquid spraying controls of cypermethrin or 48% Le Siben missible oil of making laughs, every mu of 30-60ml.

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.
