So what are the options for seed dressing when sowing potatoes? Let's take a look!

Why do you need to mix seeds before sowing potatoes

1.Seed potatoes in loading and unloading, transportation, storage during the easily infected virus or disease, if not treated, will cause cross-contamination, and planted to the ground will be rotten seeds, and disease infestation of the plant, disease.

2.When cutting seed potatoes,indoor growers the wrong cutter will cause germs to infect other healthy seeds through the cutter ...
... and infect each other in the field.

3.Because when cutting block artificially bring trauma to the potato, its wound is wet, it is easy to infect the germs and make the seed block with disease, after mixing seed with medicine, it will make the surface of the seed block trauma easy to dry and the wound easy to heal, especially the internal absorption agent can transmit to the inside of the potato block and kill the infected germs.

4.There are soil-borne pathogens in the soil, if the seed block without seed treatment is planted in the ground, it is easy to infect the soil with pathogens and make the plant with disease.

The potatoes can be used to mix the seeds of which agents

1.Seed potatoes cut, cutter to use alcohol or potassium permanganate, cut to the sick potatoes immediately change the knife and eliminate the sick potatoes in time.

2.The prevention of potato black tibia, can cut the seed potato block with methotrexate plus leaf blight or spring razamycin and grass ash or talcum powder for seed mixing.

3.Can choose 72% fenoxycarb - manganese zinc wettable powder 500 grams plus 3% in the bacteriocin wettable powder 250 grams, the second dilution of water, spray mix 1000 kg of cut seed potato block, can effectively prevent seed potato spread potato late blight, black tibia, etc.. Spray carefully and evenly, avoid heavy spraying, leak spraying; when there is wind, the nozzle as low as possible, so as to avoid the liquid drifting with the wind.

4.With gibberellin plus carbendazim dip seeds. At the time of sowing, potatoes are in a dormant state. In order to make potatoes early rooting and germination, must be broken dormant period, and rapid germination. First cut the potato seed block, put in 0.5 mg / l of erythromycin solution, plus 50% polymyxin powder 10 grams, according to the number of potato seeds to prepare the appropriate amount of solution, soak 10 to 15 minutes, pick up and filter dry, add grass ash and mix well to be sown.

5.With gibberellin plus mimosine seed soaking. Prepare a solution of 0.5 mg/l of gibberellin solution, add 25% of mimosine 1~2 ml, soak the seeds for 10~15 minutes and then strain,danish trolley stir evenly with straw ash and wait for sowing.

6.With a variety of pharmaceutical compounding seed mix. Specific operation is, every 300 pounds of potato seeds, with 100 grams of methyl tropicin, agricultural streptomycin 14 grams, sodium nitinol 5 ml, mixed with water 25 pounds of spray, require uniform. Then mix with grass ash 10-20 pounds.

Potato notes

Potato seed dressing types, commonly used to agent-based, to control potato seedling diseases, soil-borne diseases and other problems, such as methomyl, fine methomyl, cyprodinil, pyrimethanil, etc.. But for potato perennial encounter problems, can be targeted seed dressing, such as soil-borne diseases more serious, such as black mole disease, wilt, available thiflufenoxam, ethermectin, methomyl and other agents seed dressing, such as late blight more, available allyl-manganese zinc, methomyl-manganese zinc, propane-manganese zinc and other agents seed dressing, such as underground pests more serious, available imidacloprid, thiamethoxam, thiamethoxam and other agents seed dressing, but also control Aphids, lice, thrips and other insect pests in the seedling stage; the general formula can be used methomyl + thiram + streptomycin, etc., the control is more.
