Organic food production is a major direction in the development of modern agriculture. In organic peanut cultivation, the control of grubs is a key focus in the management of peanut pests and diseases. In recent years, our city has adopted a variety of methods in organic peanut cultivation, achieving remarkable results and ensuring the quality of organic peanuts.文章源自FOFCC-http://fofcc.org.cn/en/11311/
1. Agricultural control measures:文章源自FOFCC-http://fofcc.org.cn/en/11311/
1. Crop rotation. Implement a two-year, three-crop rotation system of peanut—wheat, maize (soybean) to reduce the baseline population of pests and diseases.文章源自FOFCC-http://fofcc.org.cn/en/11311/
2. Winter watering: Carry out winter watering after the autumn crops are harvested. The greater the volume of water, the higher the mortality rate of grubs.文章源自FOFCC-http://fofcc.org.cn/en/11311/
3. Fertilisation: Since grubs can live in humus, home-made organic fertiliser must be thoroughly decomposed.文章源自FOFCC-http://fofcc.org.cn/en/11311/
4. Late sowing: The sowing period in organic peanut production bases should be appropriately delayed (sowing can be around 1 May) so that more grubs move downwards to pupate after reaching maturity, thereby reducing damage.文章源自FOFCC-http://fofcc.org.cn/en/11311/
5. Manual collection: Organise the manual collection of white grubs during peanut harvesting and early spring deep ploughing to reduce the pest density and mitigate damage in the following year.文章源自FOFCC-http://fofcc.org.cn/en/11311/
2. Chemical control:文章源自FOFCC-http://fofcc.org.cn/en/11311/
Before peanut sowing, combine seed dressing and fertilising by using 180g of compound *Beauveria bassiana* per mu to control grubs. The specific method of use is: 60g for seed dressing, and 120g mixed evenly with organic fertiliser during rotary tillage and broadcast into the field, yielding excellent control results.文章源自FOFCC-http://fofcc.org.cn/en/11311/
3. Physical control measures:文章源自FOFCC-http://fofcc.org.cn/en/11311/
1. Hang electronic insecticidal lamps: From early June to early September each year, hang variable-frequency electronic insecticidal lamps (1 per 40 mu), and turn them on every evening to lure and kill adult insects.文章源自FOFCC-http://fofcc.org.cn/en/11311/
2. Unified control isolation belt: In organic cultivation, poplar trees and the like are generally planted as isolation belts. After the wheat harvest, based on the habit of chafer adults (beetles) feeding at night on tall trees such as elm, poplar and willow, all the above-mentioned tall trees are sprayed simultaneously with 40% omethoate emulsifiable concentrate at a dilution of 1:1000, or the old bark is scraped off at a height of 1 metre on the trunks of elm and poplar trees, which are then painted using a hemp brush with an 8–10 times dilution of omethoate. Because omethoate has systemic, stomach poison and contact action, and a relatively long residual effect, the control efficacy is good.文章源自FOFCC-http://fofcc.org.cn/en/11311/
3. Planting castor oil plants: Plant castor oil plants around the field to lure and kill adult chafers (scarab beetles), paralysing them before gathering and destroying them.文章源自FOFCC-http://fofcc.org.cn/en/11311/
