What diseases should be prevented and controlled during the jointing, heading, and flowering stages of wheat?

Management of pests and diseases during wheat jointing stage

Focus on preventing stripe rust, sheath blight, and stem rot, as well as preventing aphids and wheat spiders.

1. Stripe rust

Triadimefon, diniconazole, tebuconazole, epoxiconazole, propiconazole, oxystrobin, pyrazole oxystrobin, pyrimidine nucleoside antibiotic, propionazole tebuconazole, cyanene tebuconazole, propionazole tebuconazole, enoxime tebuconazole can be selected as the control agent.

2. Sheath blight

The prevention and control agents can be Jinggang Bacillus subtilis, Thiofuramide, Tebuconazole, Propiconazole, Enoconazole, Jinggangmycin, and Multiantibiotic.

3. Stem base rot

Prevention and control agents can be selected, such as propionazole, fluconazole hydroxylamine, cyanoxystrobin, cyanoxystrobin · tebuconazole, azoxystrobin · propiconazole, etc. Attention should be paid to increasing the water volume and spraying the drug solution on the base of the wheat stem to ensure the prevention and control effect.

4. Wheat spider

Avermectin, bifenthrin, mala phoxim, biphenyl triazophos and other chemicals can be selected for spray control.

Management of pests and diseases during heading and flowering period

Prevention of scab and control of midge are the main measures, while also preventing rust and powdery mildew.

1. Scab disease

In areas with frequent outbreaks, prevention should be strengthened, and medication should be administered when flowers are seen. Bacillus subtilis, Jinggang Bacillus cereus, cyanobacterium ester, propionazole, fluconazole hydroxylamine, tebuconazole, prochloraz, propionazole tebuconazole, and cyanene tebuconazole can be used. To prevent the occurrence of drug resistance, it is necessary to rotate the medication or mix it up for use.

2. Wheat midge

Adult pest control should be carried out during the heading period, using pesticides such as phoxim, chlorpyrifos, cypermethrin, chlorfluazuron, and imidacloprid. In severe areas, the drug should be administered once every 3 days.

3. Powdery mildew and stripe rust

Prevention can be carried out simultaneously during the prevention and control of scab, using methods such as cyclopropazole, cyanobacterium, propiconazole, fluconazole, tebuconazole, prochloraz, imidacloprid, imidacloprid, imidacloprid, triadimefon, and imidazole for prevention and control.

Disease and pest management during the grouting period

Prevent wheat aphids, as well as prevent powdery mildew and leaf rust.

1. Wheat aphid

Acetamiprid, imidacloprid, pirimicarb, beta cyhalothrin, matrine, otomyces and other agents can be used for spray control.

2. Powdery mildew and leaf rust

It can be combined with wheat spraying and multiple prevention measures for prevention and control, using efficient fungicides, insecticides, and micro fertilizers to scientifically mix and prevent diseases, pests, and premature aging.
