Abstract

The invention discloses a technique for controlling major diseases and insects in sowing time of wheat, which belongs to the technique of disease and insect control for crops and comprises agricultural control and drug treatment. The agricultural control includes selecting quality varieties and treating soil with drugs before sowing. The drug treatment includes treating seeds with drugs before sowing. The technique has the advantages that the plant protection policy of 'prevention first and comprehensive control' is implemented, the comprehensive control strategy of soil treatment and comprehensive mixing of drugs with seeds based on the agricultural control is implemented, strengthening of full wheat seedlings is ensured, fine foundation is laid for a good harvest of wheat in the next year, field planting test for two years shows that the technique for controlling diseases and insects for wheat can reduce diseases and insects of wheat greatly, basically no disease or insect of wheat occurs, and quality and yield of wheat are improved.

Description

The Prevention Technique of sowing stage of wheat main diseases insect pest

Technical field

The present invention relates to the crop pest control technology, specifically is the Prevention Technique of a kind of sowing stage of wheat main diseases insect pest.

Background technology

The city is the establishing in large scale zone of wheat, because the wheat growth cycle is long, pest species is many, and is very big to the Wheat Production influence.Its main diseases insect pest mainly contains soil insect such as wireworm, grub, mole cricket, powdery mildew, banded sclerotial blight, yellow rust, full rot, head blight etc.Sowing stage of wheat is first critical period of these extermination of disease and insect pest, and in that have or even unique control period, therefore, the extermination of disease and insect pest of sowing stage of wheat is very important to the full stand strong sprout and the growth in spring of wheat.Seize the opportunity, guarantee wheat full stand strong sprout, for the good harvest of next year wheat is laid a good foundation.

Summary of the invention

The Prevention Technique that the purpose of this invention is to provide the insect pest of a kind of sowing stage of wheat main diseases; Insect pest prevents and treats to main diseases at sowing stage of wheat, according to the plant protection policy of " putting prevention first integrated control "; Implementation is the basis with the cultural control; The integrated control strategy that the comprehensive seed dressing of soil treatment and medicament develops simultaneously is guaranteed wheat full stand strong sprout, for the good harvest of next year wheat is laid a good foundation.

The present invention realizes with following technical scheme: the Prevention Technique of a kind of sowing stage of wheat main diseases insect pest, and concrete grammar is:

One, cultural control

1, selects the strong kind of disease and insect resistance, avoid the unification plantation;

2, weed a garden, plough deeply soil, level land and optimize farm environment, worsen sick worm life condition, improve crushed stalk and turn over and press also field quality, reduce the next year head blight and just infect the bacterium source;

3, increase and execute the fertilizer that becomes thoroughly decomposed, meticulous whole ground, smart in good time amount, fertilizer spraying, rational application of fertilizers promotes wheat seeding early to send out, and cultivates strong sprout, improves wheat self anti-adversity ability;

4, seed selection is basked seeds: bask seeds before broadcasting and can kill the sick worm of part, and can improve germination rate and germination vigor;

Two, medical treatment

1, soil is carried out drug treating: mix fine earth before plowing and evenly spread fertilizer over the fields ground, plough under in the soil with plowing;

2, seed is carried out drug treating:

(1) kind that takes place according to damage by disease and insect selects suitable kind clothing agent to add insecticide, both can prevent and treat soil insect, can prevent and treat wheat sharp eyespot, root rot etc. again;

(2) dressing seed: not coated seed, the control soil insect is converted 4～5 kilograms in water with 50 milliliters of 50% phoxim emulsifiable concentrate or 40% Isofenphos methyl missible oil, dress seed 50 kilograms, mixes afterwards and piles vexed 2～3 hours, treat that soup fully absorbs after, dry fully and broadcast; Prevent full rot, banded sclerotial blight etc. to plant biography, soil-borne disease and soil insect; With 20 milliliters of 10 milliliters of 40% Isofenphos methyl missible oil or 40% phoxim emulsifiable concentrates; Adding wither red 50-60 milliliter or 2% Garrick show 10-15 milliliter or 2.5% of 3% enemy fits when happy the 15-20 milliliter 0.5 kilogram in water is evenly mixed 10 kilograms of wheat seeds; Mixed the back heap vexed 1-3 hour, and treated that soup all absorbed the back sowing.

The invention has the beneficial effects as follows: through the field planting evidence over 2 years,, the wheat damage by disease and insect is reduced greatly, not have the wheat damage by disease and insect basically and take place with method control wheat damage by disease and insect of the present invention.The quality and the output of wheat have been improved.

Embodiment

Further specify method of the present invention and effect below in conjunction with embodiment.

Cultural control

1, the disease-resistant worm kind of plantation.Selecting to note the kind rational deployment on the basis of anti-, anti-sick worm breeding, avoid the unification plantation.

Stimulation optimization farm environment such as 2, weed a garden, plough deeply soil, level land, worsen sick worm life condition.Improve crushed stalk and turn over also field quality of pressure, minimizing head blight in next year just infects the bacterium source.

3, increase and execute the fertilizer that becomes thoroughly decomposed, meticulous whole ground, smart in good time amount, fertilizer spraying, rational application of fertilizers promotes wheat seeding early to send out, and cultivates strong sprout, improves wheat self anti-adversity ability.

4, seed selection is basked seeds.Bask seeds before broadcasting and to kill the sick worm of part, and can improve germination rate and germination vigor.

Chemical control

Index for control: mole cricket is more than 100/mu, and grub or wireworm are more than 1000/mu.

1, soil chemicals treatment: every mu of usefulness 5% phoxim granule, or 3% Isofenphos methyl granule, 2～2.5kg; Or, convert fine earth 20～25kg with 50% phoxim emulsifiable concentrate, every mu of 100～150ml of 40% Isofenphos methyl missible oil; Full rot is retransmitted the plot, and 2～2.5 kilograms of every mu of usefulness 50% carbendazim or 70% thiophanate methyls are mixed 15～20 kilograms of fine earths, evenly spread fertilizer over the fields ground before plowing, and plough under in the soil with plowing.Sick worm mixes and sends out the field with above-mentioned two kinds of medicaments mixing use.

2, seed chemicals treatment (comprising dressing and seed dressing):

(1) kind that takes place according to damage by disease and insect is selected suitable kind clothing agent, as with 2.5% when right happy the agent of kind clothing add 40% Isofenphos methyl, both can prevent and treat soil insect, can prevent and treat wheat sharp eyespot, root rot etc. again.

(2) dressing seed: not coated seed, the control soil insect is converted 4～5 kilograms in water with 50 milliliters of 50% phoxim emulsifiable concentrate or 40% Isofenphos methyl missible oil, dress seed 50 kilograms, mixes afterwards and piles vexed 2～3 hours, treat that soup fully absorbs after, dry fully and broadcast.Prevent full rot, banded sclerotial blight etc. to plant biography, soil-borne disease and soil insect; With 20 milliliters of 10 milliliters of 40% Isofenphos methyl missible oil or 40% phoxim emulsifiable concentrates; Adding wither red 50-60 milliliter or 2% Garrick show 10-15 milliliter or 2.5% of 3% enemy fits when happy the 15-20 milliliter 0.5 kilogram in water is evenly mixed 10 kilograms of wheat seeds; Mixed the back heap vexed 1-3 hour, and treated that soup all absorbed the back sowing.
