were eating tender corn. It was Tang Guibin, a village level agricultural product quality supervisor in Qingbaijiang District, who first found the moth. “It was about six o’clock in the afternoon, and I was riding a motorcycle home from Qingquan town.” Tang Guibin recalled that his family was in group 1 of Paifang village, Qingquan town. When he passed the corn field, he slowed down a little and glanced at it. I didn’t expect that I met a moth. Half of the corn leaves were eaten away.

“corn about 50 cm high and not heading is their favorite food.” Tang Guibin said that when the corn grows to 1.8 meters high, they will not eat. After that, Tang Guibin stopped to drill into the corn field and checked line by line. “At that time, there were probably dozens of pests found, less than 100.” Tang Guibin said that he had received some training before. In the evening, he went back and sent wechat to discuss with his colleagues. He thought that it was the grassland moth.

usually include quality problems of agricultural materials such as seeds and fertilizers, preliminary quarantine of chickens, ducks and pigs, and diseases and insect pests in the fields, which are all part of his work. He is in charge of Jufeng village and Paifang village in Qingquan Town, which together have about 2000 mu of land. “Sometimes at five or six o’clock in the morning, I finish the preliminary factory quarantine for the pigs, and then I look at the crops and fruit trees on the way back.”. Early the next morning, Tang Guibin contacted Qingbaijiang agricultural and rural Bureau. More than an hour later, the staff arrived at group 1 of Paifang village. After inspection, Tang Guibin found that is the meadow moth. In just one night, the number of corn plants eaten by noctuid moth in grassland increased from less than 100 to about 300, “the expansion speed is really fast”, and about 3000 corn plants per mu will be damaged by “single moth” in a few days.

of 3000 mu dwarf corn. After that, the staff of Qingbaijiang agricultural and rural bureau sent the pesticides to the production team of group 1 in Paifang village for emergency treatment. “The effect is still good. I found that the first night, the next day we took the medicine, the third day we went to see, the insects are basically rolled up.” Tang Guibin pulled out the photo in his mobile phone and introduced that the larvae of “single moth” are hidden in the leaves of corn. They are about two centimeters long and will roll into a ball when they die.

according to the official of Qingbaijiang agricultural and rural Bureau, at the beginning of this year, all agricultural stores in the region posted “wanted notices” with portraits of Noctuidae on the grassland. “When farmers buy seeds and fertilizers, they will see that it is no longer empty talk to prevent and control the whole people for their own corn.”. At the same time, the third-party professional supervision team, such as Tang Guibin, will also go deep into the village level as an outpost for prevention and control.

have been found with diseases and insect pests, which belongs to the early stage of insect pests The person in charge said that Spodoptera exigua entered Sichuan from Yunnan, first Xichang and Panzhihua, and then gradually entered the surrounding areas (cities) and counties of Chengdu. “Those who come to us should belong to those who miss the net.”. The reason why the Qingbaijiang river was not found much also benefited from the effective control in various areas before.

Although the number of “single moths” found in

this time is not too large, in line with the control strategy of grasping early and catching small, Qingbaijiang agricultural and rural Bureau carried out a unified prevention and control for the whole area after finding the grassland Spodoptera. The planting area of corn in the whole area is about 60000 mu, including about 10000 mu of autumn corn Before the spraying control Relevant person in charge said. In addition, the frequency of field investigation has also increased from twice a week to three or four times, “early detection and timely treatment,” and “single moth” is also controllable and preventable. “.
