The most complete classification and formulation of plant diseases in history

Plant disease refers to the phenomenon that plants undergo a series of morphological, physiological and biochemical pathological changes under the influence of biological or abiotic factors, thus affecting human economic benefits. The symptoms of plant diseases are mainly divided into five types: discoloration, necrosis, decay, wilting and deformity. different diseases require different formulations, so let's take a look at them in detail.

Commonly used protective fungicides (contact fungicides): mancozeb, chlorothalonil, sulfur and copper preparations (such as Bordeaux solution, copper hydroxide, basic copper sulfate, basic copper chloride, cuprous oxide, etc.).

Commonly used internal absorption fungicides: carbendazim, methyl thiophanate, metalaxyl, triadimefon, diniconazole, difenoconazole, propiconazole, azoxystrobin, carbendazim, carbendazim, enamyl, cyanocyanide, pyrimidine, etc.

Broad-spectrum fungicides: chlorothalonil, mancozeb, methyl carbendazim (converted to carbendazim in plants, effective against spots, pink rust, Mucor, but ineffective against frost blight diseases), propionate zinc.

Frost blight disease

Main diseases: downy mildew, late blight, white rust, Phytophthora root rot, etc.

Biological prevention: Pythium oligosporium / Trichoderma / Bacillus licheniformis / berberine + sodium alginate

Chemical prophylaxis: mancozeb / chlorothalonil + polyantimycin / Wuyistin + humic acid / brown sugar

Initial formula: methyl frost manganese zinc / dialkynyl acylamide / enoyl manganese zinc / urea manganese zinc / aldicarb hydrochloride / + allicin + polyantimycin / Wuyistin + humic acid / brown sugar

Medium-term formula: fluoromycete (Yinfuli) / pyrazolyl / oxazolyl urea nitrile (Yikuangjing) / propionamide (Prik) + chlorobromoisocyanuric acid + polyantimycin / Wuyisocin + humic acid / brown sugar

Suitable for crops: leafy vegetables, eggplant fruits, melons, legumes, onions and garlic

If the epidemic disease occurs, if the level is added to one level, the speed of prevention and control should be faster.

Prevention of tomato gluten rot: take diazepam (oxime tebuconazole) + humic acid / brown sugar

Treatment of tomato gluten rot: Yinfari (fluorochloramyl) + Yikuanjing (oxone frost urea nitrile) + humic acid / brown sugar

Mucor disease

Main symptoms: grey mold, leaf mold, Sclerotinia sclerotiorum, etc.

Biological prophylaxis: Trichoderma / berberine / catechin + sodium alginate

Chemical prophylaxis: mancozeb / chlorothalonil + polyantimycin / Wuyistin + humic acid / brown sugar

Initial formula: isocourea / pyrimidine / curcumin + benzoconazole + allicin / chlorobromoisocyanuric acid + polyantimycin / Wuyisocin + humic acid / brown sugar

Medium-term formula: nicotinamide / pyrimidine cyclamine + benzimiconazole + allicin / chlorobromoisocyanuric acid + polyantimycin / Wuyisocin + humic acid / brown sugar

The formula of leaf mold: Benzoconazole + polyantimycin + allicin + humic acid / brown sugar.

The formula of coal mildew disease: isobarbamide + benziconazole + allicin.

Suitable for crops: leafy vegetables, eggplant fruits, melons, legumes, onions and garlic

Spot disease

Main symptoms: Brown spot, anthracnose, scab, leaf spot, early blight, etc.

Prevention formula: polyantimycin / Wuyisin + sodium alginate

Treatment formula: azole + allicin + polyantimycin / Wuyisin + humic acid / brown sugar

Prevention formula of scar spot disease: mancozeb / carbendazim / carbendazim / chlorothalonil + sodium alginate

Treatment formula for scar spot disease: triazoles (benzimidazole, propiconazole, flusilazole, tebuconazole) / imidazoles (prochloraz, fluromycin) / methoxyacrylates (etherin, pyrazolyl) / dicarbimide (isocarbamide) + Chunremycin + allicin + humic acid / brown sugar

Suitable for crops: leafy vegetables, eggplant fruits, melons, legumes, onions and garlic

Note: the dosage of azoles in melons and legumes is reduced by half, and eggplant fruits are used cautiously before flowering and fruit setting.

Pink rust disease

Main symptoms: powdery mildew, rust, etc.

Prevention formula: polyantimycin / Wuyisin + sodium alginate

Treatment formula: azoles / ethoxime / enoxime + allicin + humic acid / brown sugar + silicon fertilizer

Suitable for crops: leafy vegetables, eggplant fruits, melons, legumes, onions and garlic

Note: the dosage of azoles in melons and legumes is reduced by half, and eggplant fruits are used cautiously before flowering and fruit setting.

Root wilt disease

① verticillium wilt

Prevention formula: horseradish / copper acetate / copper sulfate + humic acid + EM/CM (Trichoderma harzianum can be used)

Treatment formula: carbendazim / metachlorin + Jinggangmycin / pyrimidine nucleoside / polyantimycin + rooting peptide + EM/CM

② bacterial wilt

Prevention formula: horseradish / copper acetate / copper sulfate + humic acid + EM/CM

Treatment formula: streptomycin sulfate / streptomycin / propofol / thiobactam copper + rooting peptide + EM/CM

③ Phytophthora root rot

Prevention formula: horseradish / copper acetate / copper sulfate + humic acid + EM/CM

Treatment formula: oxalic frost manganese zinc (disinfectant alum, has good effect on downy mildew, Pythium, white rust fungi) / propionamide aldicarb (Prike) + carbendazim + tocopherol + rooting peptide + EM/CM

④ stem rot
