Prevention and Control of Diseases and Insect Pests in Summer Maize Seeding Period to Seedling Stage
First, select resistant, disease-resistant varieties of high-yield, stable production, high-quality, disease-resistant, pest-resistant corn varieties. It is suggested that in the recurrence areas of maize smut and spot disease, the more resistant varieties such as Luyuandan 14, Hudan 4 and Laiyu 2 should be promoted, and Xingkang 2 and Suidan 19 should not be planted as far as possible; In the recurrence zone, Xingkang 2 and Xiyu 3 can be used; in the recurrence zone of Curvularia spp., Saitama No. 8 and Laiyu No. 2 can be selected.
Second, seed coating or pesticide seed dressing According to the occurrence of pests and diseases in recent years, targeted selection of fungicides, insecticides or special seed coating agents for seed dressing, can effectively prevent root rot, underground pests and cockroaches Horses and other pests and diseases.
1. Special coating agent coating can use 20% furoose seed coating agent, 50 ml seeds can be packaged 5 kg to 7 kg; or Yufeng harvest, 50 ml can be packaged seeds 5 kg to 7 kg, both prevention and pest control It is convenient, time-saving, and labor-saving.
2. Drug dressing 1 germicide seed dressing. Control of root rot, smut can be used 50% carbendazim or 25% triadimefon WP 100 grams to 150 grams, the right amount of water, dressing 50 kg. Prevention of maize size spot can be used corn seed dressing agent 40 grams, seed dressing 5 kilograms kilograms. The prevention of head smut can be used 6% Rickettsia suspension seed coating agent, the dosage per kilogram of seed is 1 ml to 2 ml. 2 Insecticide dressing. The main pests that injure corn are golden needles, cockroaches, cockroaches and so on. 40% phoxim EC can be used to prevent and control underground pests. The amount should not exceed 100 ml. For proper amount of water, 100 kg of corn should be mixed. Let it dry after mixing. 3 Insecticides and fungicides are mixed. For mixed areas of underground pests and corn diseases, it is necessary to vigorously promote mixed seed dressing, first mix insecticides, and then dry them and mix them with fungicides.
The main pest and weed control measures at the seedling stage are as follows:
First, the selection of corn seedling in addition to high-quality herbicides on the road, master the best period of medication, strictly according to the amount of medication operation.
1. Mu 200 ml of 40% Ethylene Mixture, 50 kg of water, spray before budding of corn.
2. Use 50% Dua Mixture 150ml for Mu, 50kg for water, spray before the 4-leaf stage of corn.
3. Mu with no trace of 150 ml, 50 kg of water, directed spray, to avoid spraying the drug on the corn leaf to prevent phytotoxicity.
4. Mu with 40% Yu Nong Suspension 50 ml ~ 100 ml, in the corn 3 leaf stage ~ 5 leaf stage spraying.
Second, seedling disease and pest control technology
1. The common pests at the seedling stage are Laodelphax striatellus, aphids, thrips, Swedish flies, corn cultivars, aphids, allergens, and various caterpillars. Laodelphax septempunctamus, aphids, or vectors for corn virus disease . Occurrence of corn cultivating land of sunflower flour can be applied with 1.5% of 1605 powder, 2kg to 3kg of finely damp soil, or 25kg of stove ash per hectare, and timely watering can improve control efficiency. The heavier swathes of the Swedish flies can be sprayed with 35% fast killer EC 45 ml or 40% omethoate EC 1000 times after 3 days to 5 days. Before controlling the third instar larvae of Mythimna separata, when there are small transparent spots on the heart and leaves, Mu with 25% diflubenzuron III colloidal suspension 30g-40g, dissolved in 40kg ~ 50kg water spray. Other pests can use 25% of Huifeng Cremophor 40ml or 2.5% of Sulfated Chrysanthemum Emulsion 25ml to 30ml, spray 50kg of water, or use 50% phoxim EC to spray 1,000 times to 1500 times .
2. Maize virus disease in the one-leaf period of corn, mu with 20% of virus A WP 500 times, spray every 7 days to 8 days, and even spray 3 times; or 1.5% of the disease with 1.5% Zhilingling II Liquid spray can effectively control viral diseases, and the corn leaves are dark green and the plants are robust. It should also adopt appropriate agricultural measures such as timely sowing, the removal of diseased plants, and the tightening of fertilization and watering.
3. Ground tigers When the damage rate of heart and leaves of corn seedlings reaches 5%, 40% phoxim EC is 1000-1500 times mu, or 2.5% is 5000-times emulsion oil 3000 kg, evenly sprayed Tigers not only spray corn seedlings but also weeds.
