The main pests in the ground are maggots, golden worms and pupa, which mainly damage the germinating seeds and break the roots of the seedlings, resulting in the lack of seedlings and ridges that affect the whole seedlings of wheat. In order to ensure the normal growth of wheat seedlings in whole seedlings and seedlings, and to provide scientific basis for the prevention and control of pests and diseases before planting, the Hancheng Plant Protection Station sampled and excavated the ground pests of reserved wheat fields at different cornices in the city's reclamation area, Sichuan Province, and mountain areas in late August. In the survey, a total of 56 plots in 12 townships and towns were investigated. The pest field rate was 95%. The city had 5,068 uniform mussels, including 6,233 for corn stalks, 4,124 for pods and 4,350 for pods. Heavy, accounting for 85% of the total number of insects, lighter than adult worms, crickets occur only sporadically in individual plots. Autumn is coming soon. It is hoped that the masses will actively take effective measures to prevent insect pests in the ground and ensure that all wheat seedlings are seeded. The specific prevention and control measures are as follows:
I. Agricultural control
1, Before sowing, it is necessary to plough, plunge, and rake into the ground to kill some of the pests in the soil through machinery and reduce the source of insects.
2, to promote balanced fertilization, pay attention to increase organic fertilizer and phosphorus and potassium fertilizers to enhance individual development and improve resistance.
3. Reasonably distribute varieties and expand planting areas of resistant and disease-resistant pests.
4. Strictly control the sowing date and prohibit the early sowing. The wheat fields in mountainous areas are planted on September 20-30, and the wheat fields in the planting areas are planted on October 1st-10th, and the wheat fields on the Sichuan-Dong irrigation area are sown on October 5-15.
Second, chemical prevention
1. Seed coating directly to buy coated seeds or 2 kg of seed coating agent per 50 kg of seed for artificial coating, drying after sowing.
2. The seed dressing for seed dressing uses 75 % 3911 EC per 50 kg seed, also 40% methylisosalt or 50% phoxim, and the dosage is 150g. Diluted with 4 kg of water and evenly sprayed on the wheat seed. On the side, stirring while spraying, heaping stuffy 8-12 hours after sowing.
III. Soil treatment mu Mixed with 40% methylisothiphos 250-300ml or 3% carbofuran granules 2kg or 1.5% of 1605 powder 5kg mixed with 25kg fine soil, mix the soil, spread the field, shallow Plow into the soil.
Precautions:
1. It is forbidden to directly contact the skin when dressing seed or coating.
2. The unfinished coating or seed dressing seeds are inedible and should be properly preserved and dealt with in time to prevent pesticide poisoning.
