Pinghu City Winter 2011 Plant Protection Technical Advice
The winter season in the autumn of 2011 is about to begin. To prevent and treat diseases and caterpillars during the winter season is an important part of ensuring the bumper harvest of winter crops and oil crops. The following opinions have been put forward on this year's winter planting and protection technology work, and technical propaganda and guidance have been strengthened throughout the country to increase the technology's availability.
I. Big wheat seed treatment
1. Barley seed treatment: (1) seed dressing: use 50% carbendazim 100 g or 43% tebuconazole 6 ml water 2 kg evenly sprayed on 25 kg of barley seeds, mix and boring with plastic film after 2-3 hours sowing. (2) Soaking: Soaking with 80% ethyl allicin EC 2000-2500 times 10-12 hours to sow dry and sowing.
2. Wheat seed treatment: (1) Seed dressing: Spray 5 kg of wheat seed with 50% carbendazim 50 g or 43% tebuconazole 6 ml plus 1 kg of water evenly. Mix well and stuff it with film for 2-3 hours. . (2) Soaking: Soaking with 20% to 2200 times of 43% tebuconazole for 10-12 hours to sow for dryness. Note that wheat cannot be soaked with ethyl allicin so as not to affect seed germination.
II. Transplanting rapeseed with rape
Apply 10% imidacloprid 10g plus 48% chlorpyrifos cream 20ml plus 15kg water spray 3-5 days before transplanting rape. Transplanting with drugs can effectively control the occurrence and damage of field locusts and cabbage caterpillars after transplanting rapeseed.
Third, weeding
It is mainly for plots with more small green grass in the Maoban field (most single-crop paddy fields can be used). Before the seedlings are transplanted before the big and wheat sowing, spray the fine fog with 41% glyphosate 100-150 g or 58% glyphosate powder 80-100 g plus 45 kg of water, so that the grass is sprayed. Grass, killing weeds in the field.
Four, weeding after sowing
(1) Weeding after wheat seedlings:
In the large, wheat after the emergence of 2 leaves 1 heart to the joint before use, per acre with 50% hypertonic isoproturon (or 50% isoproturon) 125 g or 25% isoproturon 250 g add water 45 kg drizzle rain . When the field is dry, the dosage and water consumption should be increased.
(2) Weeding After Rape:
For mono- and dicotyledonous fields: Use 17.5% of refined quinoline in the monocotyledonous weeds at the 2-3 leaf stage and 90-100 ml of water and 45 kilograms of water spray per acre (the monocotyledonous weeds in the rape field in our city Look Maiqin-based, dicotyledon dominated by cattle.
Monocotyledonous weed control: In the weeds 2-3 leaf period, use 10.8% flupiricarb per ml 30 ml or 5% quizalofop 50 ml plus 45 kg water spray. For the control of weeds in broad bean and Ziyun Yingtian, the above two agents can also be used.
For fields with miscanthus, hardgrass, bluegrass, etc.: Use 24% clethodim EC 40 ml water 45 kg spray. It is required to be used before the end of December, and it is easy to produce phytotoxicity later.
In the later period of rapeseed field (before budding), the amount of pesticides should be increased when controlling the grassland of Dao Caowang.
In addition, dry fields in Tianzhu can be sprayed with 50% acetochlor 50 ml per mu 2 days after sowing of large wheat and 1 day before transplanting rape. However, in the case of high humidity and rainy weather in the winter and bad soils, it will cause damage to large crops, wheat and rape, and should not be used.
V. Precautions
1. Herbicide application should be controlled early, to ensure the control effect, and the effect of preventing the time is too late. Prior to the allocation of large wheat crops, herbicides were stopped 7 to 10 days before sprouting to prevent phytotoxicity.
2. When using herbicides, we must pay attention to the effects of the cold wave and seize the cold tail warmer to prevent the occurrence of phytotoxicity.
3. When applying pesticides, pay attention to soil moisture, and generally use it after raining. If the soil is dry, mu water can be increased to 60 kg or used after irrigating to improve weeding.
4. Do not use long residual herbicides that have a significant effect on the growth of post-plants. In wheat fields, herbicides containing metsulfuron and chlorsulfuron should not be used. It is not advisable to use herbicides containing the aminobenzuron component in rapeseed fields to avoid phytotoxicity to the crops of the rear crops.
