The prevention and control method of peanut pests is mainly chemical control. Different pests and their occurrence in the prevention and control methods are different. The classification is introduced as follows: Other Plant Extract,Sodium Alginate Printing,Hazelnut Extract Powder,Ajuga Extract Turcosterol Youth Biotech CO,. Ltd. , https://www.youtherb.com
Aphid aphids are the main pests that harm the leaves of the locusts, causing the leaves to contract and deform and the growth to be poor. At the same time, aphids can also spread a variety of viral diseases. Therefore, it is possible to use 10% imidacloprid WP 5000x, 35% SAID 2000x, 5% rig lotion 1500x, and 3% acetamiprid 2,000 times. Liquid, etc. for prevention and treatment.
The red spider spider has a hazard period from June to August, and it occurs in drought years. Can be used 1.8% of avermectin EC 3000 times, 15% Daphthene EC 1000 to 1500 times, 40% of dicofol 1500 to 2000 times liquid spray control.
The hazard period of cotton bollworm was 6-8 months, and it was heavier in drought year. During the occurrence period of cotton bollworm, 4.5% of cypermethrin EC 1500-2000 times solution, 25% of chlorpyrifos EC 1500-2000 times solution, and methomyl EC 800-1000 times solution can be used for spraying control. It can also treat Noctuidae larvae. .
Spodoptera exigua, such as Noctuidae pests Spodoptera exigua, Spodoptera litura, Spodoptera Noctuidae and other Noctuidae pests, the situation in our province has gradually increased in recent years.
In the control of Spodoptera exigua, insect growth regulators and high-efficiency, low-toxic chemical agents should be applied. Insect growth regulators include 5% of flufenoxuron, 5% of montmorillonite, 5% of fluocinol, 5% of dinulinum, with 1500. ~ 2000 times liquid spray control in the field, can achieve 90% of the control effect. Chemicals can be sprayed with 10% of the 1500-2000 dilution of the suspension agent, 2.5% of the 2000-3000 times of the kungfu, and 4.5% of the cypermethrin EC 1500-2000 times. The above agents can also be used to treat Spodoptera litura, Spodoptera litura and other noctuid larvae.
According to the living habits of Spodoptera exigua, the best period for chemical control should be the hatching period of eggs and the larvae of 1-2 instars. The application time should be morning and evening. The peanuts should be evenly distributed on both sides. Since Spodoptera exigua is susceptible to organophosphorus and pyrethroid insecticides, pesticides should preferably be formulated with a compound or alternately.
Underground pests The main pests are mainly earthworms, followed by earthworms and golden needles. Underground pests are major pests that affect peanut germination, fruit setting, scab, yield, and quality, and can be harmful during the entire period of growth and development.
Prevention and control of groundnut pests must master the period of prevention and treatment, so as to combine prevention and control at the seeding stage with prevention and control at the growth stage, prevention and control at the adult stage and prevention and control at the larval stage. The main control object of underground pests is earthworms, which can be controlled by the following methods:
First, larval control
(A) liquid irrigation method. Per acre can choose 40% of phoxim EC 0.25-0.3 kg, 40% of the 0.25-0.3 kg of Le Siben EC, 300-500 kg of water to irrigate the roots, and can also treat other underground pests.
(b) The poisonous soil method. Per mu can be used 40% of the 0.25 to 0.3 kg of Le Siben EC, 40% of phoxim EC 0.25 to 0.4 kg, 20-30 kg of soil mix, or 5% of Tebuterin granules per acre of 1.5 to 2 Kg, 10% chlorpyrifos granules 1.5 ~ 2 kg, evenly spread around the peanut pier, watered once after cultivator better effect.
Second, adult control
(a) Use fresh sticks to trap adult insects. During adult emergence, three to five branches of fresh eucalyptus, poplar, and willow, each 60 cm long, are bundled and immersed in 75% phoxim 50 times solution or 45% simperin 50 times. In the liquid for 5 to 6 hours, insert it in the field in the evening, and insert 10 to 15 traps per mu to kill the adults.
(b) Use plant poisons to kill adult insects. Planting ramie in a peanut field can trap adult worms. The use of adults to eat ramie leaves (preferred to eat plants) caused by its paralysis, poisoning death and other effects of prevention and treatment. 20-30 ramie per mu. If the summer peanuts can be planted with castor, it is more appropriate to grow 2 to 3 leaves from the initial stage of emergence to the peak stage of the emergence of the castor, so the control effect is better.
(c) Spray control of adults. At the age of adulthood, 40% of phoxim EC 1000 to 2000 times and 4.5% of Beta-cypermethrin EC 2000 to 3000 times were used to spray on the trees around the peanut field.
(d) Manually catch adult insects. Every day evening, with a flashlight, adults are manually caught on trees such as poplar, eucalyptus, willow, and hedgehog near the peanut field. Adults to be captured and fed to poultry can be used to reduce the source of insects and ensure that the leaves of trees are not compromised.
