Preparing for the "Three Summers" | Hebei plant protection experts teach you how to control the two-point nocturnal moth

Hebei News Network News (Hebei Daily reporter Zhao Hongmei) learned from the Hebei Provincial Plant Protection Station that according to the monitoring of the relevant city and county plant protection stations, the adult generation of the two-point committee night moth has recently begun to enter its heyday in Hebei Province, with the wheat harvested from the south to the north in the province, summer sowing immediately began, all localities should immediately strengthen monitoring, scientific early warning, make full use of monitoring tools such as monitoring lights, high-altitude lamps, sex attractants, etc., strengthen the dynamic monitoring of the adult and larvae of the two-point committee night moth, and carry out prevention and control guidance according to local conditions. Prevent high-density concentrated hazards in the two-point nocturnal moth.

Plant protection experts remind farmers that the two-point commission has the following integrated control measures:

First, ecological regulation and control precautions: the two-point commission night moth is a pest that is greatly affected by ecological and environmental factors, and the following ecological control measures should be selected according to local conditions. 1. Crushing straw: Add a straw crusher on the wheat harvester, so that the stubble is not higher than 15cm, the length of the wheat straw is controlled below 10cm, and the sprinkling is even. 2. Mechanical stubble removal: After wheat harvest, the stubble machine is used to crush and compact the wheat straw and wheat stubble residue, and then sow summer corn. 3. Clean up the corn sowing row wheat straw: use the ridge clearing machine, the corn ridge clearing planter, the sowing row rotary tillage planter, the planting machine is configured on the planter, and the manual cleaning method is used to remove the sown row wheat straw; the horizontal distance between the corn planter trencher and the fertilizer spreader can also be adjusted to about 10cm to clean up. 4. Remove wheat straw outside the field: Apply mechanical or manual straw balers to remove wheat straw outside the field.

Second, seed coating: the use of butyl thiocritifer, bromocyanamide and other components of seed coating agent for seed coating.

Third, combined with early prevention and control of weeding. During the sowing to emergence period of summer maize, chemical weeding can be combined with chemical weeding, and the agents such as methylaminoavermectin benzoate and chlorhexabenzamide can be selected for the plots without ecological control measures and sprayed uniformly throughout the field for adult and young larval control.

Fourth, larval emergency control. If the number of insects in 100 plants reaches 6, and the rate of corn seedlings being killed reaches 3%, the bait, spray and other methods are immediately used to control it. Bait booby trap: Use methylaminoavermectin benzoate, chlorantran benzamide, insecticide and other agents to dispense the bait, and place it in the evening around the root of the cleared corn, taking care not to sprinkle on the corn. Pharmaceutical spray: Before the 6-leaf stage of maize, for the larvae of the elderly two-point nocturnal moth, the sapling of methylamino avermectin benzoate, chlorantrane benzamide, karyotype polyhedral virus and other agents can be selected for spray control, spraying along the ridge or spraying the rhizome directly with a sprinkler.
