“You must pay attention to prevention and treatment. We have found wheat stripe rust in your house.†On March 3rd, the technical staff of the plant protection station of the Agriculture and Animal Husbandry Bureau of Shunqing District was in the corn field of Pear Garden Village, Jintai Town. We are busy with helping farmers identify and prevent diseases and pests in Xiaochun.
“This year's wheat stripe rust has been characterized by early occurrence, rapid spread, and a wide variety of diseases.†According to Wu Junfang, deputy director of the District Agriculture and Animal Husbandry Bureau, two strip rust centers were found in Xiaoheba Village, Dalin Township, on January 7 this year. The disease group, which covers an area of ​​1 square meter, was found to be the first disease on March 8 last year, 60 days in advance. “Although effective prevention and control have been implemented, the situation is still not optimistic and needs to be highly valued by the farmers.†Wu Junfang said that over the past three to four months, low-temperature, cold and strong convection weather has been frequent, and the introduction of foreign germplasm has been very favorable. Wheat stripe rust has been introduced. The situation will be even more severe. According to their survey of Tongren, Jintai, Lijia, Gongxing and Dalin townships, up to now, there are still 22 central disease groups in the district, with a maximum area of ​​2 square meters.
"As long as proper precautions are taken, wheat stripe rust can be controlled." According to Wu Junfang, farmers can use triadimefon WP and diniconazole spray application to prevent the spread of disease hazards. Wu Junfang said that in the next stage, they will further increase the intensity of the wheat stripe rust early-onset area, often-prone areas, re-emerging areas, the cultivation of susceptible varieties and the wind mouth valley area survey. The diseased sporadic diseased plots were promptly cleared of diseased leaves, buried deep in the field, and sprayed on the wheat seedlings within one foot of the diseased leaf to prevent and control the onset center and the entire plot. Discovered a point, a piece of control, found a piece, a piece of control, control the wheat stripe rust in the stage of spotting.
It is understood that this year, the wheat planting area in the region reached 83,000 mu. To ensure that farmers increase production and increase income, the region has actively adjusted the planting structure in response to the characteristics of the region's wheat prone to stripe rust, which has reduced the annual density and incidence of wind rust in strip river rust. Early wheat planting area in the old ward; increasing the replacement of wheat varieties, the promotion rate of Chuanmai 47, Chuanmai 42, Chuanmai 46, Chuanong 26, Chuanyu 20, Chuanmai 43 and other fine varieties reached over 90%; With wheat seed dressing, the seed dressing rate of the towns along the river reached 90%, and the remaining townships had a seed dressing rate of 80%, which effectively reduced winter germs, reduced the spring pressure, and laid a foundation for increasing wheat production and income.
Soybean branching period or early flowering period with 5% of Uniconazole WP can be 24-48 grams or 15% of paclobutrazol wettable powder 50-70 grams, watering 40-50 kg evenly spraying stems and leaves.
Soybean seedlings will focus on the prevention and control of the blackfly, Saccharomyces visinalis, and will be applied on the 7th, 15th, and 21st days after emergence, or during the occurrence period of the black fly, and sprayed with 1000 times of 50% phoxim EC per acre; In order to control the root rot in time, use 50% thiophanate-methyl WP or 65% zein zinc WP to water 50 kg stem-leaf spray per mu; pay attention to the control of locusts and spider mites in the whole growing period. Mu with 50% anti-inferiority WP 15 to 30 grams or 2.5% to Fortune EC 15 to 20 ml diluted 50 kg water spray.
5. timely harvest. During the waxing stage, the corn presses the lower leaves and retains the three-leaf rods; during the yellow ripening stage, the harvesting ears are harvested and the corn stalks are immediately cut and covered in situ.
It is advisable to harvest the soybeans from yellow to ripe and harvest them, then dry them and dry them to thresh.
