I. Rice blast
In mid-July, the rice break period is 20-30 g of 75% tricyclazole, or 40-50 ml of water is added to the hand for 50-60 kg of manual spray, and the rule is 1-2 times.
Second, rice sheath blight
At present, the incidence of sheath blight in the field has reached 5-90%, with an average of 36.7%. Therefore, when the field disease rate reaches 20-30%, it should be applied immediately. Mu with 20% stalk net sp25-35 with water 50-60 kg manual spray.
Third, the second case of rice aphids to attract moths is: the first day of seeing the cockroaches on June 11th, the end of June 23, the moths will be 17, the big cockroaches will begin on June 12, June 23 46 moths were trapped, and Sanhua was seen on June 1st, and on June 23rd, the moths were 3-4 (due to new survey points, no historical data).
. .
The first generation of locusts on June 24 was detached in the field: larvae and ticks of Daphnia and Sanhuai were not stripped, and second-instar larvae accounted for 2.17%, third-aged accounted for 21.7 4%, and fourth-aged accounted for 2 3.91%, the second age accounted for 21.74%, the sixth age accounted for 23.91%, and the sputum accounted for 6.5 2%.
In summary, the prevention and control of the second generation of aphids should still be dominated by the mites and cockroaches, and the treatment of mites and mites. The control period: July 13-22. During this period, the first rice field will be applied first, and the rice field will be applied after the broken rice field. The unbroken rice field will be applied at the last time of the control period (the paddy field for the treatment of mites can be used to prevent neck lice. Mixed application).
Control drugs and methods: use 17% enemy 螟80-90m1 for mu, or 20% Thunder ec80ml for acre, or 5% Regent sc30-40ml for acre. Water spray 5 0-6 0 kg manual spray.
4. Rice leaf roller is improved due to improved farming system, frequent variety changes, ecological environment changes, and the reproduction of natural enemies. Therefore, the insect has risen to become the main pest in the late rice period, and all areas must strengthen field investigations. When the new worms are 15-20, immediately use 1 7% of the enemy 螟80-90m 1, or 5% Regent 30-40ml with 50-60 kg of manual spray.
