According to investigations at all stations in the Xinjiang Grain and Oil Region, most grain crops and other economic crops in the northern Xinjiang grain and oil planting region have entered the peak period of pests and diseases, especially the occurrence of diseases, which poses a serious threat to agricultural production.
I. Occurrence and forecast of current pests and rodents The key period for the management of various types of cash crops in the Corps has recently come to the forefront. The most important part of management at this stage is the prevention and control of pests and diseases. The forecast of the occurrence of some pests and rodents is as follows:
1. Melon black leeches: According to a survey station of the 181 regiment of the Nongshi Shishi, black spot disease appeared on some plots of Hamigua in July.
In areas where some melons are more concentrated, due to more precipitation in August and higher temperatures, it is conducive to the spread of diseases.
2. Fighting melon powdery mildew: According to a survey conducted by the 181 regiment, the incidence of powdery mildew was 3%, and individual plots were slightly heavier. Powdery mildew occurred in part of the 185 masses.
According to the long-term forecast in August, the precipitation is slightly more normal, and it is expected that the occurrence of powdery mildew will occur.
3. Oil sunflower Sclerotinia: According to a survey conducted by the station of the 181 regiment of the Nongshi division, the average incidence rate was 12%, and the degree of occurrence was heavy, especially in fields with long continuous cropping periods.
According to the long-term forecast in August, the normal rainfall is slightly higher. It is expected that the S. sclerotiorum disease will occur more seriously and some regions will be severely affected.
4. Maize leafhoppers: According to the survey station of the 84th regiment of the Agricultural Fifth Division, the occurrence of cornfield crops was mainly truncated leafhoppers. Especially since mid-July, there has been continuous high-temperature weather in the country, causing corn spider mites to gradually occur in the corn fields. And local heavier. The individual plant plots have a rate of 10-30%, and the average planting rate is about 5%, which is currently harmed in the lower corn leaves.
Combining with the weather forecast, the occurrence and historical data of corn truncate leafhoppers and other factors, it is expected that the occurrence of corn truncated earthworms in Ili district will occur moderately and occur locally. The flood season is in mid-August.
5. Rat damage: A survey of the mice monitoring stations of the 181th Agricultural Division was conducted. The rate of capture on July 24 and 25 was 11.15%. The rate of pregnancy in females was 19%, and the male to female ratio was 79. Young rats already accounted for 12% of the capture rate. The mice have already begun their activity hazards and will become new breeding colonies by the end of the year. The breeding peak in July has passed. The survey results showed that the number of fetuses is currently 4, the breeding rate is high, and the proportion of females is high; in field investigation, pests have caused serious damage in some areas.
The recent weather is conducive to the occurrence of rodent pests and breeding hazards. It is predicted that autumn rat damage will take place in most grain and oil special crop areas.
II. Prevention and Control Recommendations 1. According to the recent climatic conditions in most grain and oil-specific croplands, which are conducive to the occurrence of diseases, the special grain and oil special areas will strengthen the investigation of diseases, pests and rodents, publish pest and disease pests in a timely manner, and formulate emergency prevention and control measures. Especially for diseases and rodents, attention must be paid to strengthening prevention.
2. For the prevention and control of diseases, especially the serious occurrence of melon diseases, all units must protect and control spraying, and control the disease in the initial stage.
3. Strengthen the monitoring of corn truncated leafhoppers and timely organize the people to carry out prevention and control of spread and spread. Do a good job of water and fertilizer operations to prevent the corn from dehydration from the drought, enhance resistance, light field can be promptly cut off the lower part of the insect leaves. Heavy fields can be fumigated or sprayed for control. Special acaricides can be used, 1.8% of avermectin, 1.8% of eucalyptus cream, and 15% of fennel oil 2000-2500 times spray.
4. Sclerotinia: After the flowering of sunflower and sunflower, if it is found to be rotten, Sclerotinia sclerotiorum should be promptly carefully removed to bring the diseased plant into the bag and take it out of the field.
5. Rats: At present, all units are ready for autumn rodent rodent control to achieve the purpose of controlling rodents. Rodenticide Select poisonous sodium salt, bromadiolone, etc. The Ministry of Agriculture has a higher safety rodenticide to configure the baits, choose no rain at night, the bait will be piled up, and piled at 5 to 8 grams per 5 square meters. The prepared poison baits are directly placed in the dark place where the rodents are often active and cannot be spread. All units have established a strict system for safekeeping and storage of rats, ensuring safe use.
6. Strict use of pesticides in strict accordance with the provisions for the safe use of pesticides, and the use of five organophosphorus pesticides such as monocrotophos, methamidophos, parathion, methyl parathion and phosphoamine, which are prohibited by the State, are strictly prohibited.
