Prevention and control methods

Pine borer EC, 50% Bataan aqueous solvent, 50% methamidophos emulsion or 50% 1605 emulsifiable concentrate, 100 ml per mu, 150 200 kg of water poured out.

2. Use 150 ml of 40% dimethoate EC and 100 ml of 50% dimethoate EC per mu, add 200 300 kg of water and pour it, or halve the amount of medicine per mu and spray it with 50 kg of water.

3. 1 2 days before the peak of ant borer hatching, 60 80 ml of 50% pyrimidine phosphorus oxychloride emulsifiable concentrate per mu was sprayed with 75 100 kg of water.

4. Use 50 100 grams of 50% Yiwei soluble powder per mu and spray it with water.

5. Use 75 100 ml of 50% quick-extinguishing pine EC per mu and spray with water.

6. Use 2 kg of 5% Acrylic granules per mu.

The rice leaf roller borer is controlled at the peak stage of egg hatching. For light occurrence, use 50 ml of avermectin or 45 ml of avermectin per mu, mix 15-30 kg of water (increase the water consumption according to the growth of rice and insect conditions), and spray it once in 15 days.

For recurrence (generation re-prosperity), 75-100 ml of avermectin or 70-100 ml of avermectin per mu can be sprayed once every 10 days.

The above content reference: Encyclopedia - Rice borer.

Spraying control must be carried out in the peak period of adults and larvae hatching.

You can choose 2500 to 3000 times of Efudin EC, 800 times of BT WP, which should be applied or selected as soon as possible, or 21% killing EC 2000 times, 20% chrysanthemum or 10% chrysanthemum EC 1000 times, or Kung Fu EC 3000 times;

or 10% Dolaibro suspension 2000 times, or 20% fenvalerate EC 3000 times, or 5% Lefering EC 3000 times, or 10% Uranus EC 3000 times;

Or 2,500 times of emulsifiable concentrate from 100 trees, or 3,000 times of emulsifiable concentrate for killing enemies, or 100 times of chlorpyramide No. 3 suspension.

Rice borborer can be controlled with agents such as Bacillus thuringiensis, chlorantraniliprole, fluorbolea, tetrachlorantraniliprole, fiproramide, perchloramectin benzoate and so on. In order to reduce pest resistance, attention should be paid to alternating the rotation of pesticides.

1. 8 grams of Fugo or 40 ml of Liangtai + 50 grams of thiazinone + 12 ml of 50% difenoconazolepropiconazole emulsifiable concentrate per mu are used to treat rice planthoppers, rice borers, rice leaf rollers and sheath blight, as well as other diseases and insects.

2. 100 ml of 3% emamectin mite urea or 30-40 ml of 5% avermectin + 40 grams of 25% thiiso wettable powder per mu are used to treat rice leaf roller borer and rice planthopper.

Rice borer now generally refers to the two borer, at present in the control of the two borer, the agent is still limited, and the control effect is not satisfactory. Let's talk about the prevention and control of the two borers according to practice, and the occurrence of large borers and three borers is limited, which will not be introduced in this article.

The control time of the borborer.

The control time of the heartworm is very critical, the eggs are not hatched too early, and the effect of the stalks can not be reached if the eggs are not hatched too early. We generally recommend "insect control without insects, prevention at the peak of eggs", that is, the most appropriate time to use the drug when the egg hatching peak, this criterion is that the field wilt rate of 2%-3% can be applied when the pesticide can be applied, or see the stalk began to turn red to start the drug. Medication should be taken sooner rather than later.

Selection of coreworm control agents.

The first choice of diamide insecticides for preventive drugs: chlorantraniliprole, flubenziliprole, tetrachlorantraniliprole, can also be appropriately mixed with insecticidal bis, insecticidal mono, chlorpyrifos, etc. When the base number of insect population is large:

High-dose avermectin, flubelluron, emamectin, etc. can be used. When applying pesticides, pay attention to ensure water consumption, it is generally recommended to have more than 120 catties of water per acre, and it is not recommended to use aircraft to apply pesticides. It is better to maintain a 3-5 cm aquifer in the field.

Conclusion: The prevention and control of the two borers is also a comprehensive process, in recent years, the two borers are also seriously related to rice varieties, etc., for the fields with a large base of the two borers, it is recommended to irrigate and plough in winter to reduce the base.

Rice borer special medicine - Hot Wheels suspension. 20% fenozide + Demin Xin unique formula. It has special effects on rice borer (two or three borer) and rice leaf roller. Eggs and insects are killed, and the effect is seen on the same day. The validity period is about 30 days.

Hot Wheels suspension. Of course, DuPont Kangkuan is also good, but it is a lot more expensive.

Rice borer, three borer, big borer, these three kinds of borer, have the common name of borer, the prevention and control of rice borer, should be used before the larvae drill into the rice plant, generally in the egg incubation period, the larvae drill into the rice plant after the application effect is often poor.

At present, most of the rice dead hearts are caused by the two borers, which have the habit of transferring plants, and one larva can cause multiple stem tillers to dry hearts.

Prevention and control of diphos, in the peak period of egg incubation, the application of chlorpyrifos, avermectin and its mixture with insecticides and other commonly used drugs, there is a good control effect, the application of diazinphos, butene fipronil (similar to fipronil is one of the best drugs for the prevention and control of diborer), chlorantraniliprole, fiproramide, cyanopronizone and other drugs also have good control effect. Among them, diazinphos, butylfipronil, chlorantraniliprole, and fiproramide have good systemic conductivity, and when the appropriate period of prevention and control is missed, the dimorph borer has been bored into the rice leaf sheath and other parts when the pesticide is applied, which also has a good control effect, and can effectively reduce the harm of the two borer transplantations.

Henan Dexi Yangnong's rice king star has a special effect on rice concentration insects. You can take a look.

Rice borer is effective with Kangkuan pesticide pesticide. Special drugs for the prevention and control of rice borerworm. 1. The special drugs for the prevention and control of rice borer worm include Ruijinte, Lesben, Sutering, Rice Farmer No. 1, Special Killing Borer and other medicines.

Mu with 5 Ruijin special suspension 40-50 ml Laoqing code or 48 Lesben 50-60 ml spray control, the control effect is good, with broad spectrum and long-lasting effect, can also treat gray planthopper, rice weevil. When the insect load is large, the second control should be carried out 5-7 days after the treatment. 2. Biological pesticides include Suterin, Rice Farmer No. 1, Tertorial borer, etc., which can be used before the peak of egg incubation and low difference imitation age, and can be treated with 51 Rice Farmer No. 1 50 grams or 46 Tertorial borer 60 grams per mu, and sprayed with kilograms of water for prevention and control.

3. Alternate use of a variety of agents, not a single dose of a large amount. In case of windy days or expected rain within 1 hour, do not apply the pesticide. Maintaining a shallow water layer of 3-5 cm for 3-5 days during the medication period can improve the efficacy of the drug.
