Application technology Take 20% fenvalerate emulsifiable concentrate as an example.
(1) Control cotton pests
① Cotton bollworm is used in the peak period of egg hatching, and it is sprayed evenly with 20% fenvalerate EC diluted 2000 times. Due to the serious resistance in recent years, it is mostly used in combination with organophosphorus insecticides such as phoxim, or mixed with commercially available insecticides. agent. In the case of a large amount of eggs and a long egg period, it needs to be sprayed once every 3~5 days.
② Cotton red bollworm is diluted 2000 times with 20% fenvalerate EC and sprayed evenly during the egg hatching period. The resistance of cotton bollworm in the middle and lower reaches of the Yangtze River has gradually increased. Longer-term organic phosphorus mixed use.
(2) Prevention and control of oil crops and commercial crop pests
① Bean pod borer and soybean borer Spray evenly with 20% esfenvalerate EC 300mL/hm2 mixed with water.
② For tobacco aphids and tobacco budworms, use 450~600mL/hm2 of 20% fenvalerate EC to mix with water and spray evenly.
(3) Control wheat pests
For wheat aphids and armyworms, spray evenly with 3000-5000 times of 20% fenvalerate EC, and mix with fungicides when there is powdery mildew or head blight at the ear stage.
(4) Prevention and control of fruit tree pests
① Peach borer and pear borer are in the egg hatching stage, when the egg-fruit rate reaches 1%, dilute 2000~4000 times with 20% fenvalerate EC and spray evenly, it has killing effect on larvae or eggs, From the first hatching stage to the newly hatched larvae stage, it can be used continuously for 2 times.
② Aphids, caterpillars, inchworms, sting moths, leafminers, leaf tortrixes, pear net bugs, psyllids, peach borers, codling moths Spray evenly with 1500-2000 times of 20% fenvalerate EC.
(5) Prevention and control of vegetable pests
① Pieris rapae and diamondback moth Dilute 2000-3000 times with 20% fenvalerate EC and spray evenly at the 2nd to 3rd instar larvae. At the same time, it can control cabbage aphid and Spodoptera litura, but it is ineffective against resistant diamondback moth.
② Cabbage aphid and thrips: Spray evenly with 20% fenvalerate EC 300~600mL/hm2 mixed with water.
(6) Prevention and control of tea tree pests
For tea loopers, tea caterpillars, slug moths, tea fine moths, and black thorn whiteflies, spray evenly with 2000-3000 times of 20% fenvalerate EC.
Precautions
(1) For several years of continuous use of cotton bollworm and cotton aphid, severe resistance has developed in most areas, so it should be stopped or mixed with other pesticides.
(2) It is highly toxic to fish and aquatic organisms, so it is forbidden to use it in the control of pests in rice fields, and it should be used in sericulture areas, and it should also be kept away from mulberry fields.
(3) It should be used with caution in the prevention and control of tea tree and vegetable pests, which may easily cause excessive residues, affect tea export or cause pollution problems.
