Bela plesen in pojedeni listi na kosmulji

Lani se mi je na kosmulji pojavila plesen ker se bojim da bo letos isto Vas prosim da mi pomagate z nasveti kako to zatreti na čim bolj naravni način.Grm kosmulje je velik in vsako leto obilno obrodi.Lani nismo obrali niti ene ker so bili plodovi obdani s plesnijo.Ker je kosmulja med ostalim jagodičjem se bojim da se bo plesen prenesla na ostale rastline.Prosim za pomoč ker mi kosmulja že zeleni.

Na kosmulji imaš ameriško kosmuljevo plesen, ki se zelo težko odstrani, vsekakor pa boš morala po kakšno škropivo v rastlinsko lekarno, ker domači zvarki niso učinkoviti. Grme predvsem razredči, potem pa bo treba škropiti. Imena škropiva ti pa ne morem svetovati.

Tudi pri nas imamo doma kosmulje, ki jih zadnje čase napada plesen (hvala Lisi za točno poimenovanje), zato sem zadevo malo pogooglala in našla naslednje relevantne nasvete:

Zatiranje bolezni ni enostavno, saj je precej trdoživa. Pomembno je, da opravimo predpomladansko škropljenje s sredstvo vivera cuprablau. Kasneje v vegetaciji (ko so listi že razviti) pa opravimoše škropljenje s sredstvom vivera rubigan v odmerku 3-4 ml/10l vode. Močno okužene poganjke porežemo.Ribez ima rad humusna tla, zato je priporočljivo, da vsako leto spomladi dodamo grmu tri pesti gnojila plantella organik, ki bo povečalo odpornost rastline na bolezni in sušo, poleg tega pa bo pridelek bolj zdrav.

Non-chemical control

A number of measures will help reduce occurrence of the disease;

Gooseberries are best pruned to an open form to aid picking. This also discourages stagnant air amongst the branches and promotes the circulation of airAvoid planting in low-lying or enclosed areas or with poor air flowOpening up bushes will also greatly ease picking and control of gooseberry sawflyAvoid excessive quantities of nitrogen rich manure, dried poultry manure pellets for example or mulching with manure, because the resulting soft growth is more readily attackedA dressing of a balanced fertiliser, such as Growmore, is more suitable – use 50g per sq m (1½oz per sq yd)The fungus overwinters within the buds and on the shoots, and (with blackcurrants in particular) on fallen leaves. It is therefore essential to 'tip' prune the bushes by removing and disposing of (bonfire or shredding and composting) the ends of affected shoots as soon as they are seen, as well as disposing of all fallen leaves in autumn

Eating affected fruit

The fungal growth on the berries can be rubbed off, and the gooseberries are edible, so there is no need to waste the crop if many of the fruits are affected. However, even after this laborious process the diseased berries will turn brown when cooked.

Resistant cultivars

Organic gardeners, and gardeners who find spraying ineffective, can grow resistant cultivars which can offer a useful level of resistance to this disease:

Gooseberry cultivars

'Captivator': Resistant
'Greenfinch' AGM: Resistant
'Hinnomaki Gold': Slightly Resistant
'Hinnomaki Red': Resistant
'Hinnomaki Green': Resistant
'Invincta' AGM: Resistant (Although young plants of this variety show moderate attacks of mildew the shoots of mature plants and fruits are highly resistant)
'Martlet': Resistant
'Pax': Slightly Resistant
'Remarka': Resistant
'Rokula': Resistant

[...]

Chemical control

The fungicides myclobutanil (Systhane Fungus Fighter) can be used to control this disease and spraying should be carried out according to the manufacturer's instructions.

A product containing a blend of plant and fish oils (Organic 2 in 1) is also available and can be used by organic gardeners. It acts by physical, rather than chemical, action.

Tega škropiva VIVERA CUPRABLAU ne morem kupiti ker nimam izkaznice o nekakšnem opravljenem izpititu.Tako da to škropivo ne pride v poštev.Ali je mogoče ta cuprablau modra galica, ker če je to res potem je to strupeno.

Sicer cuprablau očitno ni isto kot modra galica, je pa vse eno škodljiv za okolje:

Alternativa mešanica rastlinskih in ribjih olj, vendar pa ne vem kje oz. če sploh lahko tako zadevo dobiš na našem trgu, poleg tega gre pa tudi za drugačen način delovanja, kot se omenja v zadnjem podčrtanem odstavku.
