I. Rice blast In the middle and early July of July, rice breaks use 75% of tricyclazole in 20-30 grams of mu, or 40-50 ml of rice in mu, and 50-60 kg of water in hand. The system is controlled 1-2 times. Head and neck. Second, rice sheath blight At present, sheath blight disease incidence in the field has reached 5-90%, an average of 36.7%. Therefore, when the disease rate in the field reaches 20-30%, the pesticide should be applied immediately. Mu with 20% net dry sp25-35 water 50-60 kg hand spray. 3. The situation of the moth moth under the second generation of rice locust locusts is as follows: on the 11th of June, the second phase of the locust infestation began, and on the 23rd of June, there were 17 lure moths, and on June 12th, the locusts only met on June 23rd. 46 moths were attracted, three of them had seen on June 11th, and 34 had trapped moths on June 23rd (there was no historical data due to the new monitoring point). . . The field deprivation of the first generation locusts on June 24 was: the larvae and pupae of the larvae and the three larvae were not scavenged. The second-instar larvae of the second-stage larvae accounted for 2.17%, the second-instar larvae accounted for 21.74%, and the fourth instar accounted for 2 3.91%, the fifth instar accounted for 21.74%, the sixth instar accounted for 23.91%, and the nevus accounted for 6.5 2%. In summary, the prevention and control of second-generation locusts this year should still be dominated by pupa and big borers, and they should also be used to control the three-phase locusts and control the appropriate period: July 13-22. During this period, rice fields that broke first were first applied to rice fields, and rice fields that had been breached were applied afterwards. Rice fields that had not been breached were applied at the last time during the appropriate period of control. Mixed application). Drugs and methods for prevention and control: Mu with 17% enemy ec80-90m1, or mu with 20% Thunder ec80ml, or 5% Rui Jin special sc30-40ml. Watering 5 0-6 0 kg manual spray. 4. The rice leaffolder is improved due to improved farming systems, frequent species changes, changes in the ecological environment, and reproduction of natural natural enemies. Therefore, the insect has risen to become the main insect pest in the later stage of rice, and field investigations must be strengthened when there are When 15-20 new insects are infested, they immediately use 7% enemy enemy ec80-90m1 per mu, or 5% Ruijinte 30-40ml watered 50-60kg hand spray.
